Question

Find the area of a circle with a diameter of 16

Answer 1

Answer: A = 64$\pi$ = 201.061

Step-by-step explanation:

The equation to find the area of a circle, is:

$A=\frac{1}{4} \pi d^2$

-Next, you place the diameter onto the equation:

$A=\frac{1}{4} \pi 16^2$

-Then, you solve:

$A=\frac{1}{4} \pi 16^2$

$A = \frac{1}{4}$$\pi$ × $256$

$A=\frac{256}{4} \pi$

$A=64\pi = 201.061$

Answer 2

Answer:

201.06

Step-by-step explanation:

Area of circle: $A=\pi r^2$

r = 1/2d = 1/2(16) = 8

$\pi *8^2 = 201.06$
