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!
Find the volume of a sphere of radius 9 meters?
V = 3,053.6 cubic meters.
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?
What is the volume to the nearest tenth of a sphere with a radius of 9 centimeters?
4/3 * pi * 9^3 = 3054.5cm cubed
A mug in the shape of a cylinder has base with a radius of 4 cm How many milliliters of liquide does it hold if filled to height of 9 cm?
A mug in the shape of a cylinder has base with a radius of 4 cm How many milliliters of liquid does it hold if filled to height of 9 cm? Volume of a cylinder = area of base * height Base is a circle Area of a circle = π * radius squared The radius = 4 cm Area = 3.14 * r * r = ____ square cm Area = 3.14 * ___ * ___ = ____ square cm Volume of a cylinder = area of base * height You know area of the base and the height = 9 cm. Volume of a cylinder = ______ * _____ = _____ cubic cm 1 cubic cm = 1 milliliter 150 cubic cm = 150 milliliter Answer ≈ 450-455 ml
