A: Area
r: Radius
A = π r²
25 = π r²
r = √(25/π) cm
Radius, r = 5/√π cm
Radius, r ≈ 2.82 cm
r: Radius
A = π r²
25 = π r²
r = √(25/π) cm
Radius, r = 5/√π cm
Radius, r ≈ 2.82 cm

A = pi * r^2
25 = pi * r^2
5 = sqrt(pi) * r
5 / sqrt(pi) = r
5 * sqrt(pi) / pi = r
25 = pi * r^2
5 = sqrt(pi) * r
5 / sqrt(pi) = r
5 * sqrt(pi) / pi = r
