Find the surface area of a sphere with a diameter of 78 use 3.14 for pi?
The surface area of a sphere with diameter 78 and using 3.14 for Pi is about 19,103.76 units2
If you know the diameter of a sphere you can find its surface area?
Yes, that's true. The surface area is (the square of the diameter) multiplied by (pi).
How do you find the diameter of a sphere when you have the surface area?
Using the formula for the surface area of a sphere, which is SA = 4 (pi) r2, you can find the radius, and the diameter of the sphere is twice the radius. Example: If the surface of a sphere is 380 square cm 4 (pi) r2 = SA 4 (3.1416) r2 = 380 12.5664 r2 = 380 r2 = approx. 30.24 r = 5.5 and diameter D = 11 cm
How do you find the total surface area of a hemisphere whose diameter is 8 inches?
Calculate the radius (it is half the diameter).Use the formula for a sphere: area = 4 x pi x radius2.Since a hemisphere is half a sphere, divide this result by 2.Question:Do you mean the surface area to include the flat face of the hemisphere?If so then follow the above instructions and add pi*42 to your answer which will give you the complete surface area of the hemisphere.
How do you find the curved surface area of sphere?
Surface area of a sphere = 4*pi*radius2
