How do you find the area of a sphere?
4 * pi * radius * radius or (pi * diameter * diameter) / 3 Also ( 4 * 3.14 * radius squared ) Also ( 88/7 * radius squared )
Formula to find out the Earth's surface area?
The Earth is close enough to a sphere, so you can use the formula for a sphere: 4 x pi x r2. "r" is the radius; if you find the diameter of Earth somewhere, divide it by 2 to get the radius.The Earth is close enough to a sphere, so you can use the formula for a sphere: 4 x pi x r2.

Formula to find radius of a sphere?
Depends on the information that you DO have. Half the diameter is the easiest formula, but that only works if you know the diameter.
Find the surface of a sphere whose diameter is d?
Surface area of a sphere in square units = 4*pi*radius^2
What are the volume and radius and diameter of Mars?
Mars is almost a sphere and the volume of a sphere is: 4/3*pi*radius3 So find its radius and its volume can be found using the above formula
Find the diameter of a sphere 1.5m. and find the radius?
If the diameter is 1.5m then the radius is 0.75 m. If the diameter is not 1.5m then it what is 1.5m?
How do you find the diameter of a sphere?
R (radius) X2. The radius is half the circle from the center of the circle. The diameter is just straight across.

Find the surface of a sphere whose diameter is d?
Surface area of a sphere in square units = 4*pi*radius^2
What is the diameter of a 5 pound sphere?
You need to know it's density to find the volume, then 4/3 pi r^3 to get radius, then double radius is diameter.
What are the volume and radius and diameter of Mars?
Mars is almost a sphere and the volume of a sphere is: 4/3*pi*radius3 So find its radius and its volume can be found using the above formula
How do you find the surface area of a sphere to the nearest square meter?
-- You have to ask somebody for the radius of the sphere, in meters. If they tell you the diameter instead, then the radius is 1/2 of the diameter, in meters. -- Multiply (4) times (pi) times (the radius)2 . That's the surface area of the sphere, in square meters. -- Round the answer to the nearest square meter.
How do you find the volume of a sphere knowing the diameter?
Reverse the equation. Volume x 3/4 x 1/3.1416 = cubed root of radius. The radius is one half the diameter.
How do you find the diameter of a sphere when you have the surface area?
Using the formula for the surface area of a sphere, which is SA = 4 (pi) r2, you can find the radius, and the diameter of the sphere is twice the radius. Example: If the surface of a sphere is 380 square cm 4 (pi) r2 = SA 4 (3.1416) r2 = 380 12.5664 r2 = 380 r2 = approx. 30.24 r = 5.5 and diameter D = 11 cm
How do you find the diameter of a sphere with a given volume?
Make the radius the subject of the formula 4/3*pi* radius3 = volume and then double it to give the diameter.
