The surface area of this sphere is 2,123.7 units2676 units2
The surface area of a sphere with a radius of 15 units is 2,827 units2
Surface area of a sphere = 4*pi*radius2 Surface area = 4*pi*112 = 1520.530844 square units.
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.
Circumference isn't squared OR cubed. However, Surface Area is squared and so is Area. So Circumference is just Circumference :)
The approximate surface area of a sphere with circumference 37.68km is 452km
Surface area = 53.794 units2
S = C2/pi where S is the surface area, C is the circumference.
circular calculations. circumference, area of circle, vol of sphere, surface area of sphere, etc.
You can divide this problem into two steps: 1) Divide the circumference by (2 x pi) to get the radius. 2) Use this radius in the standard formula for the surface area of the sphere.
4*pi*r2. because surface area is equal to circumference of circle.
The great circle has circumference 40pi and we know circumference is 2pixr so 20 is the radius of the sphere. Now use this and the formula that surface area is 4pir^2 so the surface are is 4pi(20)^2. or pi(1600)
There is no such thing as an "area of circumference".If 27 cm is the diameter, you can calculate the circumference by multiplying this by pi, which is approximately 3.1416.
They can be: volume, surface area, radius, diameter, circumference, axis and its hemisphere
pie times diameter is the circumference of a circle. a sphere is a 3-dimensional object and you dont take the circumference but rather you take the surface area. the circumference is to measure the total outside distance around the circle. the surface area is the measure the total outside distance around the sphere. remember a sphere is like a ball that is rounded. a circle is just a circle and can only be 2-dimensional.. like on paper
The area of a sphere is equal to its circumference times its diameter.There are a variety of ways to work out this formula, most of them involving calculus.(See the links for the volume of a sphere).
You are correct my friend! Surface Area of a Sphere is indeed = 4(pi)r^2 and that is also equal to Circumference times Diameter!
