Question

Find the circumference and area of a circle with a diameter of 22 inches. Leave your answers in terms of pi.

C = 11π; A = 44π

C = 22π; A = 44π

C = 11π; A = 121π

C = 22π; A = 121π

Answer 1

C= 22(pi); A=121(pi)

Answer 2

Circumference = pi * diameter....so circumference = pi * 22
Area = pi * r^2......keep in mind that r = 1/2d...so r = 11.
Area = pi * 11^2.....Area = pi * 121

Answer 3

so is it c=11(pi) A=121(pi)

Answer 4

C = 22(pi) and A = 121(pi)

Answer 5

ok thanks

Answer 6

sure thing :)
