Sounds like another homework question.... here's everything you'll need....
The formula for surface area (A) of a sphere, radius "r", is A=4*pi*r2
The formula for volume (V) of a sphere, radius "r", is V=4*pi*r3/3
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
A sphere with a volume of 50 units3 has a radius of 2.29 units. A sphere with twice the radius (4.58 units) has a volume of 402 units3.
The formula for the volume of a sphere is based on the radius of the sphere. It is equal to 4/3 multiplied by pi, multiplied by the radius cubed.
4/3*pi*r3 = 30 cubic units Make r the subject of the formula in order to find the radius: radius = 1.92757321 units 2*radius =3.85514642 Volume = 4/3*pi*3.855146423 = 239.9999998 or 240 cubic units
Use this formula when the radius is known: V = 4/3(PI*r3)
use algebra to find the radius, then plug the height and radius into the surface area equation
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
Given a sphere of radius r, Surface area = 4{pi}r2 Volume = (4/3){pi}r3
Use the formula for the volume. Replace the data you know (radius and volume), and solve for the missing data (the height). Once you have this height, it is easy to use the formula for the surface area.
You cant find it unless you know another value like the volume or surface area.
4*pi*radius2 = area radius = square root of (area/4*pi) diameter = 2*radius volume = 4/3*pi*radius3
The volume of a cone can be calculated using the formula V = (1/3)πr^2h, where r is the radius and h is the height. To find the radius, use the formula A = πrℓ, where A is the curved surface area and ℓ is the slant height. Given A = 550 cm and h = 25 cm, you can find the radius and then calculate the volume of the cone.
It is not possible to find the volume from the two radii. That will only give the surface area of the disk that it forms. To find the volume yYou also need the thickness of .
First we have to find the radius: 4*pi*radius2 = 64*pi Divide both sides by 4*pi and then square root both sides to find the value of the radius: radius = 4 cm Volume of a sphere = 4/3*pi*radius3 Volume = 268.0825731 or 268 cm3 to the nearest cubic cm
To calculate the weight of the basketball filled with mercury, first calculate the volume of the basketball using the formula for the volume of a sphere. Then, convert the volume to liters (1 L = 1000 cm^3) to determine the mass of the mercury in grams. Finally, divide the mass by 1000 to convert it to kilograms.
Volume=(pi)(radius^2)(height)
Volume = about 56.55 units3
