Find the circumference and area of a circle with a diameter of 10 inches. Leave your
answers in terms of pi.
O C = 51: A = 20
O C = 10; A = 20
O C = 10; A = 25T
O C = 5T; A = 2511

Answer 1

Area = πr^2

= π * 5^2

= 25π

Circumference = 2πr

= 2 * π * 5

= 10π

Answer 2

C= 10, A= 25

Explanation:

d= 10 in

r= d/2= 5 in

C= 2πr= 2π*5= 10 π in

A= πr²= π*5²= 25 π in²
