How do you work out the area of a sphere?
To work out the area of a sphere, you have to know its radius. Once you know that: -- 'square' the radius (multiply radius times radius) -- multiply that result by 12.5664 The result is near the area of the sphere.
'What is the surface area of a sphere with a radius of 5 m?
The surface area of a sphere with a radius of 5m is 314.2m2
If the radius of a sphere is tripled what is going to happen to surface area?
If the radius of a sphere is tripled, the surface area increases by (3)2 = 9 times, and the volume increases by (3)3 = 27 times.
If the radius of a sphere is tripled how is the surface area affected?
The surface area of a sphere is directly proportional to the square of its radius. A ∝ r2 r = 3k A ∝ (3k)2 A ∝ 9k2 therefore, the surface area will become 9 times the size

What is the surface area of a sphere with diameter 18 CM?
Oh, dude, you just need to find the radius first, which is half of the diameter, so that's 9 cm. Then you use the formula for the surface area of a sphere, which is 4πr^2. Plug in 9 for r, square it, multiply by 4, and then multiply by π. That gives you a surface area of 1017π square cm, or about 3190 square cm. Easy peasy!
