Question

Find the diameter of a circle whose are area is 254.34cm2

Answer 1

Circle
Solve for diameter
d≈18cm
A Area

254.34
cm²

Answer 2

area =πr^2

therefore

πr^2=254.34

22×r^2/7 = 254.34

r^2=254.34×7/22

r^2=80.926363636

r=√80.926363636

r=8.9959081607

d=2×r

=2×8.9959081607

=17.991816321
