If the radius of a sphere is doubled, the surface area increases by (2)2 = 4 times,
and the volume increases by (2)3 = 8 times.
The surface area of a sphere with a radius of 15 units is 2,827 units2
The radius is 4.5135
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.
The surface area of this sphere is 2,123.7 units2676 units2
If the radius of the hemispheres is 4, then that leave 4 units for the length if the straight part of the cylinder. Total surface area = surface area of 1/2 sphere of radius 4 + lateral surface area of cylinder of radius 4 and height 4 + surface area of 1/2 sphere of radius 4. = surface area of sphere of radius 4 + lateral surface area of cylinder of radius 4 = 4*3*pi*43 + pi*42*4 = 469.1 cubic units.
The surface area of the sphere with the radius doubled is 200 units2.---> Confirmed
the surface area quadruples.
The surface area of a sphere with a radius of 2 is about 50.27 units2
The surface area of a sphere with a radius of 4.75 is about 283.5 units2
The surface area of a sphere with a radius of 13ft is about 2,123.7ft2
The surface of a sphere is: A=4? r2 From this, the surface are changes as the square of the radius. It does not change linearly.
The surface area of a sphere with a radius of 5m is 314.2m2
The volume is proportiuo9nal to the cube of the radius, so doubling the radiuscauses the volume to increase to (2)3= 8 times its original value.
The surface area of a sphere that has a radius of 10 is: 1,260 square units.
The surface area of a sphere with radius 6 is: 452 square units.
Finding the radius of a Sphere by using the surface area is a multi-step mathematical equation. The radius (r) of a sphere with a surface area of 1742400ft is 372.365ft.
The surface area of a sphere with a radius of 15 units is 2,827 units2
