Question

find the surface area of a sphere with radius 3.5 CM​

Answer 1

r=3.5cm

s.a of sphere=4π r^2

=4(22/7)(3.5)^2

=4(22/7)(3.5)(3.5)

=4(22/2)(3.5)

=4(11)(3.5)

=4(37.5)

=150.0 cm^2

Answer 2

Answer

154cm^2

Explanation:

Surface area of sphere= 4πr^2

=4×22/7×3.5×3.5

=4×22/2×3.5

=44×3.5

=154cm ^2.
