Circumference Formula:
$C = 2\pi \times R$
R = Radius = 15 in

$C = 2\pi \times 15$
$C = 30\pi \: inches$

Find the circumference of this circle. Round to the nearest tenth.<br><br> Area= 63.6 inches squared

Virty [35]

Answer:

C = 28.048

Step-by-step explanation:

Circumference = 2pi(r)

Area = pi(r)^2

62.6 = pi(r)^2

r^2 = 62.6/pi

r^2 = 19.926

r = 4.464

Therefore, circumference = 2pi(4.464)

= 28.048
