The sphere has surface are of 900π m².

Step-by-step explanation:

Given,

Diameter = d = 30m

Radius = $\frac{d}{2} =\frac{30}{2} = 15m$

Surface area of sphere = $4\pi\ r^2$

$Surface\ area = 4*\pi *(15)^2\\Surface\ area = 4*\pi * 225\\Surface\ area= 990\pi$

The sphere has surface are of 900π m².
