Answers

Answer 1

Answer:

v = 628.32 m³

Step-by-step explanation:

v = πr²h/3

v = π(20/2)²(6)/3

v = π(100)(2)

v = 628.318530718

Rounded

v = 628.32 m³

Answer 2

This is what I got 628.32m^3

find surface area of the prism pls!!!!! explain too. I really need help!!!

Answers

i believe you have to multiply meaning 6x5x2 it’s 60.

Answer: 104 square inches

Step-by-step explanation:

The surface area of a prism is the sum of the surface are of all of it's faces.

We can turn that into this equation SA = 2(w x l) + 2(l x h) + 2(w x h) where w is width, l is length, h is height, and 2(w x l) is the top and the bottom surface areas, 2(l x h) is the left and right sides, and 2(w x h) is the front and back.

Substitute to get this: SA = 2(6 x 2) + 2(2 x 5) + 2(6 x 5)

Simplify with multiplication to get this: SA = 24 + 20 + 60

Simplify with addition to get this: SA = 104

Add the unit label and you get 104 square inches.

The following triangle is an isosceles triangle. What is the length of the missing side?
A. 4 in
B. 37°
C. 53°
D. 11 in

Answers

Answer:

D.11 in

Step-by-step explanation:

isosceles triangles have two congruent sides

The missing side length is congruent with the longer side ( this is pretty obvious )

If the longer side has a length of 11in and the missing side is congruent to the longer side then the missing side length equals 11 in

[Help Please!] Find the value of x.

Answers

Answer:

x = 52

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles of a triangle

x+72 = 34+90

x +72 =124

Subtract 72 from each side

x = 124-72

x =52

Answer:

x = 52 degrees

Step-by-step explanation:

Let's first focus on the angle x + 72. Immediately adjacent to x + 72 is angle RQS. These two angles are "straight" in that they lie immediately adjacent to one another and add up to 180 degrees. Then angle RQS can be expressed as

180 degrees - (x + 72 degrees), or 108 - x degrees.

The three interior angles of the triangle must add up to 180 degrees. Hence

108 - x degrees + 34 degrees + 90 degrees = 180 degrees, and so:

108 - x + 34 = 90

This yields x = 52 degrees.

Answer:

The numbers are 8 and 6

Step-by-step explanation:

Let x and y be the two numbers

x+y = 14

x-y = 2

Add the two equations together

x+y = 14

x-y = 2

--------------

2x +0y = 16

Divide by 2

2x/2 = 16/2

x = 8

Now find y

x+y = 14

8+y =14

Subtract 8 from each side

8+y-8 =14-8

y =6

The numbers are 8 and 6
