Answer:

15 inches

Step-by-step explanation:

Perimeter is 2l + 2w (or l+l+w+w)

Start by subtracting: 42 - 12. The 12 is from 2•6 for both width sides.

42-12=30

Divide 30 by 2 to find the length for one side. 30 ÷ 2 = 15

The area of a circle is 16π cm2. What is the circle's circumference?

agasfer [191]

Answer:

C = 8 pi cm

Step-by-step explanation:

A = pi r^2

16 pi = pi r^2

Divide each side by pi

16 = r^2

Taking the square root

4 = r

The circumference is

C = 2 * pi *r

C = 2* pi *(4)

C = 8 pi cm
