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!
The formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere. Since the diameter is 18 cm, the radius is half of that, which is 9 cm. Plugging this into the formula, the surface area of the sphere is 4π(9)^2 = 324π square cm.

What is the surface area of a sphere with diameter 18 feet?
The surface area of a sphere with a diameter of 18 feet is: 1,020 square feet.
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
What is the area of a 18 inch diameter circle?
The area of a 18-inch diameter circle is: 254.5 square inches.
A sphere has a surface area of 18 square centimeters. What is the volume of a sphere?
9 √(2/pi) We start with the formulas for surface area (4 pi r^2) and volume (4/3 pi r^3). If 4 pi r^2 = 18, then r = 3/√(2 pi); plug that into the formula for volume and we get 9 √(2/pi) as the answer.
