The equation for the surface area of a sphere is 4∏R2
Insert values for r
4x(pi)x32
4x(pi)x9
4x9=36pi
36xpi = 133.076 units2
A = 4 (3.14159)(32)
A = (4)(3.14159)(9) = 113.097
A = about 113.1 square units

When was the formula for the area and volume of a sphere created?
Impoved Answer:-Surface area of a sphere: 4*pi*radius squaredVolume of a sphere: 4/3*pi*radius cubed
Relation between volume radius and surface of sphere?
Let the radius of the sphere be r. surface area of the sphere = 4 * pi * r^2 volume = (4 * pi * r^3)/3
How to find the surface area and volume of a sphere with a given radius.?
Given a sphere of radius r, Surface area = 4{pi}r2 Volume = (4/3){pi}r3
What is the surface area of a sphere with a radius of 2?
SA of a sphere = 4pi(radius)^2 SA = 4(3.14)2^2 SA = 50.24
Formula for finding volume and area of sphere?
Volume = 4/3 * pi * radius * radius * radius Surface Area = 4 * pi * radius * radius

Relation between volume radius and surface of sphere?
Let the radius of the sphere be r. surface area of the sphere = 4 * pi * r^2 volume = (4 * pi * r^3)/3
What is the surface area of a cylinder with end that are half sphere with a radius of 4 and height of 12?
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.
What is the Volume and surface area of sphere?
surface area = 4(pi)(radius)^2 volume = (4/3)(pi)(radius)^3 hope this helped!
