Diameter: 41/pi = 13 inches rounded to a whole number
Radius: 13/2 = 6.5 inches
Surface area of the sphere: 4*pi*6.5 squared = 530.929 square inches to three decimal places
Divide the circumference by (2 x pi). That gives you the radius, which you can use in the standard formula for the sphere's surface area.
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.
A sphere with a surface area of 324pi cubic inches has a volume of: 3,054 cubic inches.
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.
The approximate surface area of a sphere with circumference 37.68km is 452km
Surface area = 53.794 units2
The surface area of a sphere with a diameter of 8 inches is 201.1 inches2
S = C2/pi where S is the surface area, C is the circumference.
A sphere with a surface area of 324pi cubic inches has a volume of: 3,054 cubic inches.
circular calculations. circumference, area of circle, vol of sphere, surface area of sphere, etc.
The surface area of a sphere with a diameter of 2.7 inches is about 23 square inches.
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.
The surface area, to the nearest tenth, of a sphere that has a diameter of 14 inches is: 615.8 inches2
The surface area of a sphere with a diameter of 25 inches is about 1,963.5 square inches.
The surface area is 314.16 inches2
Radius = 23.565/(2*3.142) = 3.75 inches Volume = 4/3*3.142*3.753 = 220.921875 cubic inches Surface area = 4*3.142*3.752 = 176.7375 square inches
