Fan & Medal / Please helpppp
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

Answer 2

Circumfrence is 2pi(r)

C = 2pi(r)

Radius in diameter / 2
r = d/2 -> r = 22/2 -> r = 11

So C = 2pi(11)

Answer 3

Which is C = 22pi

Area is pi(r)^2

We know r = 11

A = pi(11)^2

A = pi(121)

Answer 4

\[C = 22\pi \]
\[A = 121\pi \]

Answer 5

thank you so much!!!
