What else can I help you with?
If you know the diameter of a sphere you can find its radius true or false?
True. The radius is half the diameter.
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.
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.
How can you use radius to find the diameter?
you double the radius to find 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 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.
How do you find diameter from radius?
diameter = 2*radius
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 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
