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!

TaigaOh, what a happy little question! To find the surface area of a sphere, you can use the formula 4πr^2, where r is the radius. Since the diameter is 18 cm, the radius is half of that, which is 9 cm. Plugging that into the formula, the surface area of the sphere is 4π(9)^2 = 324π square cm.

What is the surface area of a sphere whose diameter is 18 cm?
Oh, dude, you're hitting me with some math here. So, the formula for the surface area of a sphere is 4πr², where r is the radius. Since the diameter is 18 cm, the radius is half of that, which is 9 cm. Plug that into the formula, and you get a surface area of 1017π cm². But like, who's really gonna measure that in real life, am I right?
When making a snowman with an 18 inch diameter top sphere and a ratio of 1 to 2 to 3 in the diameters of the other spheres what will the diameters of the other spheres be?
If you have an 18 inch diameter sphere on top, you'll have a 36 inch diameter sphere in the middle and a 54 inch diameter sphere on the bottom. 18 x 2 = 36 and 18 x 3 = 54
