A semi circle is half a full circle. Find the area of the full circle and divide it by 2.
Area of a circle = pi x r ^2
R is half the diameter
Area of full circle:
Area = 22/7 x 21^2
Area = 1386 sq. Ft
Area of stage = 1386/2 = 693 square feet
Answer:
3.14 x 42 x 42 = 5538.96ft
If your wondering why used 3.14 instead of 22/7 is because they are exactly the same just one is a whole number and the other is a fraction. I suggest you use 3.14 because its easier than 22/7.

4th grade math helplolll
Answer:
175 dollars
Step-by-step explanation:
from that word problem the equation that i was able to get out of it was
1225/ 7
^ the travel allowance and how much days they are going to be there
i dont know if you are allowed to use a calculator in your class but puting 1225/ 7 does give you a answer of a positive number of 175 dollars
meaning that they can only use 175 dollars a day so they dont go over the allowance
i hope this helps you! please stay safe and have a good day :)
Answer:
Um, the answer for that is 175.
Step-by-step explanation:
all you need to do is divide $1,225 by 7 which is 175.

Find the measure of each labeled angle A(3x-20) B(2x) C (2x-15)
Answer:
Measure of angle A = 100°
Measure of angle B = 80°
Measure of angle C = 65°
Step-by-step explanation:
From the given picture,
Angle A and angle B are the linear pair of angles, and linear pair of angles are supplementary angles,
m(∠A) + m(∠B) = 180°
(3x - 20)° + (2x)° = 180°
5x - 20 = 180
5x = 200
x = 40
By substituting the value of x in the measures of each angle,
m(∠A) = (3x - 20)°
= 3(40) - 20
= 120 - 20
= 100°
m(∠B) = 2x°
= 2(40)
= 80°
m(∠C) = (2x - 15)°
= 2(40) - 15
= 80 - 15
= 65°
A car drove 5 miles in 30 minutes. How far will the car go in 1 hour?
Answer: 10 miles
Step-by-step explanation:
Practically, just look at it. 30 minutes = 5 miles, 60 minutes = 10 miles
Mathmatically, find the constant of proportionality.
30 minutes divided by 5 miles = 6 minutes per 1 mile. 60 minutes = 10 miles

A child toy is made by removing a triangular prism from the center of a wooden rectangular prism The triangular base of the triangular prism has a base length of 1 inch and a height of 1 inch. Write and solve an equation to find the volume of the toy.
*see attachment for the diagram given
Answer:
Volume of the toy = 68 in.³
Step-by-step explanation:
The equation to find the volume of the toy = volume of the wooden rectangular prism - volume of the triangular prism removed form the center
Volume of the toy = (L*W*H) - (½*bhl)
Where,
L = 8 inches
W = 3 inches
H = 3 inches
b = 1 inch
h = 1 inch
l = 8 inches
Plug in the values into the equation
Volume of the toy = (8*3*3) - (½*1*1*8)
Volume = 72 - 4
Volume of the toy = 68 in.³
pls helpppppp !!
tysmmmm <33
Answer:
180
Step-by-step explanation:
From basic rules of a triangle we know that the interior angles of a triangle have to add up to equal 180°
But here is a formula for future references for finding the sum of the interior angles
interior angle sum = (n-2)180
where n = number of sides
and here is an example:
a triangle has 3 sides so we plug in 3 for n
(3-2)180
3-2=1
1*180 = 180
so the interior angles add up to equal 180
You place two wooden support beams under a shelf, as shown. Find the value of x
Answer:
17x
Step-by-step explanation:
so first 2x is 2 x x = 2x
then +10 =12x then 5 + x = 5x so 5x + 12x = 17x

Which pairs of polygons are congruent? A. pairs 1, 2, 3, and 4 B. pairs 1 and 4 C. pairs 1, 2, and 3 D. pairs 2 and 4
plz tell about congruent and similar triangles
Similar: If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.
____________________________________________________________
Congruent: SAS stands for "side, angle, side" and means that we have two triangles where we know two sides and the included angle are equal. If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.

can someone please help me with this question?? (no links!!!)
Answer:
960
Step-by-step explanation:
it says use 3 for pi, so you plug the values into given equation
V = 3·(4)²·20
r is 4 because it is half of 8.
Then multiply
3·16·20 = 48·20 = 960
Answer:
960 cm
Step-by-step explanation:
8/2 = 4 (radius)
3 (since we're using 3 for pi) * 4^2 * 20
3 * 16 * 20
48 * 20
= 960 cm

x/3 less than or equal to 7
Answer:
x ≤ 21
Step-by-step explanation:
x/3 ≤ 7
x ≤ 21
Answer:
x ≤ 21
Step-by-step explanation:
With this problem, we have to solve for x, and to do that, we isolate the variable.
To do this, let’s get rid of the /3 from the x by multiplying both sides by 3
now we get x ≤ 7 times 3
finall, we get x≤21
