Question

What will be the area and D perimetre of an 11.5cm circle

Answer 1

Answer:

given:-

perimeter=11.5

perimeter=circumference

if circumference is 11.5(given)

To find radius:-

Circumference=2πr

11.5=2×22/7×r

r=7×11.5/2×22

r=885.5cm

if radius of a circle is 88 5.5 then diameter of the circle is equals to 88 5.5 into 2

therefore the diameter is 1771cm

Area is equals to πr^2

therefore area is equals to 8 8 5.5× to 22\ 7 ×2

Area=5566cm^2

Hope it helped!
