The surface area of a sphere is directly proportional to the square of its radius.
A ∝ r2
r = 3k
A ∝ (3k)2
A ∝ 9k2
therefore, the surface area will become 9 times the size
The surface area of a sphere with a radius of 2 is about 50.27 units2
The surface area of the sphere with the radius doubled is 200 units2.---> Confirmed
The surface area of a sphere with a radius of 7 is about 615.8 units2
a. 2 to 5.
It depends on the shape. The volume of a sphere will increase differently to the volume of a cylinder, for example.
If the radius of a sphere is tripled, the surface area increases by (3)2 = 9 times, and the volume increases by (3)3 = 27 times.
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 area of a sphere with a radius of 2 is about 50.27 units2
The surface area of a sphere with a radius of 5m is 314.2m2
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 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 the sphere with the radius doubled is 200 units2.---> Confirmed
The surface area of a sphere with a radius of 12 units is about 1,809.6 units2
The surface area of a sphere with a radius of 15 units is 2,827 units2
