Answer:

50.24

Explanation:

The formula for solving circumference is 2 x pi x r

first the radius is 8 (divide 16 by 2 and get radius)

( pi can be 22/7 or 3.14. but I’m taking 3.14 )

second, we have all values, now we just have to substitute them!

Pi = 3.14

R = 8

so when we do 2x 3.14 x 8 = 50.24

I hope this helped!

Answer: The area of the circle is 64π cm

Explanation:

d=16→r=8

A= π⋅8 ^2

A= π⋅64

A=64π
