C

Step-by-step explanation:

The circumference (C) of a circle is calculated using

C= 2πr ← r is the radius and has to be found

Given C = 20π , then

2πr = 20π ( divide both sides by 2π )

r = = 10

The area (A) of a circle is calculated using the formula

A = πr² = π × 10² = 100π m² → C

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :
