Question

Work out the surface area of this sphere 2.6cm

Answer 1

A = 27.04π cm²

Explanation:

The surface area of a sphere of radius r is A = 4πr²

If the radius, r, is 2.6 cm, then the surface area here is A = 4π(2.6 cm)², or

A = 4π(6 .76 cm²) or

A = 27.04π cm²

Answer 2

If 2.6 cm is the radius!! then the answer is 84. 95

Explanation:

A = 4pie(radius)^2

2.6^2=6.76

6.76*4*pie
