18 km
3247 km2
Ob
4227 km2
Ос
3447 km
Od
12967 km2

Answer 1

Surface area of the figure = 1,296π km²

Explanation:

Given figure is a sphere;

Given:

Radius of sphere = 18 km

Find:

Surface area of the figure

Computation:

Surface area of the figure = Surface area of sphere

Surface area of sphere = 4πr²

Surface area of the figure = 4πr²

Surface area of the figure = 4π(18)²

Surface area of the figure = 4π(324)

Surface area of the figure = 1,296π km²
