What is the formula for calculating the area of a sphere?
Therefore, the Surface Area of a Sphere with radius r equals 4πr2 . Example : Find the surface area of a sphere with radius 5 inches.
How do you find the volume and area of a sphere?
Sphere Formulas in terms of radius r:
- Volume of a sphere: V = (4/3)πr.
- Circumference of a sphere: C = 2πr.
- Surface area of a sphere: A = 4πr.
What is TSA of sphere?
T.S.A of sphere = 4πr2.
Is TSA and CSA of sphere same?
Since the sphere is a complete curved shape therefore the curved surface area is equal to the total area of sphere. It is also called lateral surface area. Surface Area of Sphere = 4πr², where r is the radius of sphere.
Which is the shape of cylinder?
A cylinder has two flat ends in the shape of circles. These two faces are connected by a curved face that looks like a tube. If you make a flat net for a cylinder, it looks like a rectangle with a circle attached at each end.
What is the perimeter of a sphere?
Say the perimeter of a unit cube is 12, because that’s the sum of all its edges, hence it’s the cube’s perimeter….What’s the perimeter of a sphere?

How do you find the area of a sphere?
To find the surface area of a sphere you can use the following formula: Area = 4 π r². In an easier to read form: Area = 4 * Pi * r * r. Sometimes a sphere is given a north and south pole (found on opposite sides of the surface).
What is the approximate surface area of the sphere?
The surface area of a sphere is equal to [4 x Pi x R^2]. In other words, four multiplied by 3.14 multiplied by the radius squared. If the radius of a sphere is 15 yards, the approximate surface area is [4 x 3.14 x (15×15)] = [12.5 x 225] = [2,812 yd^2]. The surface area of a sphere with radius 15 yd is approximately 2,800 yards. 1.6. 16 votes.
How do you calculate the radius of a sphere?
Calculate the radius of the sphere from the information given about the sphere. If you know the diameter (distance through the sphere through the center), divide by two to find the radius. If you know the circumference (distance around the center of the sphere), divide by 2π.
How do you calculate a sphere?
Sphere size is calculated using two measures: the volume (how much space the sphere takes up) and the surface area (the total area of the sphere’s surface). Both sphere size and surface area can be easily calculated if you know the radius or diameter of the sphere. The formula for volume is 4/3 times pi times the radius cubed, or 4/3πr^3.
