how to find the area of a circle with the diameter of 30

Answers

Answer 1
A = pi x r^2
r = 30/2 = 15
A = pi(15^2)
A = pi(225) or
A = 3.14(225) = 706.5

This is circle theorems I am not rly good at this

Answers

Answer:

m∠BCD = 24°

Step-by-step explanation:

By the theorem,

"Angle subtended by an arc at the center of the circle is twice in measure of the angle subtended at the circumference."

m(∠BOD) = 2(m∠BFD)

                = 2(78°)

                 = 156°

Therefore, m(arc BD) = m∠BOD = 156°

Since, m(arc BD) + m(arc BFD) = 360°

156° + m(arc BFD) = 360°

m(arc BFD) = 360 - 156

                   = 204°

Since, "angle formed outside the circle by the intersection of two tangents measure half of the difference of the intercepted arcs".

m∠BCD = [tex]\frac{1}{2}[m(\text{arc BFD})-m(\text{arc BD})][/tex]

              = [tex]\frac{1}{2}[204 - 156][/tex]

              = 24°

Juan has a piece of fabric with a length of 5/9 yard and a width of 3/10 yard. What is the area of Juan's piece of fabric? Enter your answer as a fraction in simplest form by filling in the boxes.

Answers

The area of the given cloth is 1/6 yards².

What is an area?The measurement that expresses the size of a region on a plane or curved surface is called an area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

So, the area of the cloth:

The length of the cloth is 5/9 yards.The breadth of the cloth is 3/10 yards.

So, we know that it is a rectangular cloth.

Area of rectangle: l × b

Calculate the area as follows:

l × b5/9 × 3/1015/901/6 yards²


Therefore, the area of the given cloth is 1/6 yards².

Answer:

348 of them are not postgraduates

Step-by-step explanation:

Answer:

348

Step-by-step explanation:

Out of 725 employees, 52% are postgraduates.

First find the percentage who are not postgraduates, or the "remaining."

100% - 52% = 48%

48% of 725 employees = how many employees?

48/100 × x/725

Cross multiply

48 × 725 = 100 × x

34800 = 100x

Divide both sides by 100

34800 ÷ 100 = 100x ÷ 100

348 = 1x

348 employees are not postgraduates

solve for x. round to the nearest tenth

Step-by-step explanation:
In order to evaluate the function f(x)=x^4+6x^3+3 for x=2, you must replace all of the x's with the number two and then simplify:
f(2)=2^4+6(2)^3+3
f(2)=16+6(8)+3
f(2)=16+48+3
f(2)=16+51

Why is the radius 4?

Answers

Answer:

Please check explanations

Step-by-step explanation:

The equation of a circle can be represented as;

(x-h)^2 + (y-k)^2 = r^2

r is the radius while (h,k) represents the coordinates of the center

Thus, we have that;

(x-2)^2 + (y+3)^2

That would give;

x^2 - 4x + 4 + y^2 + 6y + 9

The sum of values with no coefficient is;

4 + 9 = 13

If we take this to the other side, we can have 13 + 3 = 16

The square root of this is then 4

Mathematically, we can therefore express the equation of the circle as;

(x-2)^2 + (y-+3)^2 = 4^2

By expansion, we will get the original given equation
