Question

if the area of a circle is 314msq then it's diameter will be what

Answer 1

pi * r^2 = 314
3.14 * r^2 = 314
r^2 = 100
r = 10m

Diameter = 2r = 20m

Answer 2

heya mate

here your answer goes like this

Given,

Area of circle = 314.sq.m

=> pi × r^2 = 314 ((( pi = 22/7 )))) ((((( r = radius))))))

22/7 × r^2 = 314

r^2 = 314 × 7 / 22

r^2 = 100 {{{{{ round up value }}}}}}

r = 10m

but diameter = 2r

so, 2× 10 = 20m



thanks !!!
