Find the circumference of a circle, Mathematics

Assignment Help:

Find the circumference of a circle whose area is 16 times the area of the circle with diameter 7cm            (Ans: 88cm)

Ans:     Π R2 = 16 Π r2

R2 = 16 r 2

R2 = 16 x 7/2  x 7/2

= 49 x 4           ⇒ R = 7 x 2 = 14cm

Circumference = 2 x 22/7 x 14 = 2 x 22 x 2 = 88 cm
