What is the equation for the surface area of a sphere?
Surface area of a sphere with radius r = 4(pi)r2
What is the total surface area of this sphere radius4?
The surface area of a sphere with radius 4 is about 201 units2
What can you use to find the sphere surface area?
Surface area of a sphere = 4*pi*radius squared
What is the surface area of a sphere with a radius of 10 meters?
The surface area of any sphere is (4 pi) x (radius)2 So the surface area of this particular sphere is (4 pi) x (10)2 .
What is the radius if area of a sphere is 4 meter square?
If the surface area of the sphere is 4 m2, the radius is 0.5642 metres, approx.
What is the total surface area of a sphere when the radius is 4?
The total surface area of a sphere when the radius is 4 equals 201.1 units2
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.
If the radius of a sphere doubles does its surface area double?
No, if the radius of a sphere doubles, its surface area increases by a factor of 4, not simply doubling. The surface area of a sphere is proportional to the square of the radius.
What is surface area of spherical shell?
Surface area of a sphere = 4*pi*radius2 For a spherical shell, surface area = surface area of outer sphere - surface area of inner sphere = 4*pi*(outer radius)2 - 4*pi*(inner radius)2 = 4*pi*[ (outer radius)2 - (inner radius)2 ]
What is 4 times pi times the radius squared is the surface area of a sphere?
That is correct because the surface area of a sphere is: 4*pi*radius squared
What is the equation for the surface area of a sphere?
Surface area of a sphere with radius r = 4(pi)r2
What is the total surface area of this sphere radius4?
The surface area of a sphere with radius 4 is about 201 units2
What can you use to find the sphere surface area?
Surface area of a sphere = 4*pi*radius squared
What is the surface area of a sphere with a radius of 10 meters?
The surface area of any sphere is (4 pi) x (radius)2 So the surface area of this particular sphere is (4 pi) x (10)2 .
What is the radius if area of a sphere is 4 meter square?
If the surface area of the sphere is 4 m2, the radius is 0.5642 metres, approx.
What is the surface area of a sphere with a radius of 4?
The formula for the surface area of a sphere is 4 (pi) r2For a radius of 4, the surface area is4 (3.1416) (4)2 = 4 (3.1416)(16) = about 201.06 square units
If the surface area of a sphere is increased by a factor of 4 what is the change in the length of the radius of the sphere?
The area of a sphere is A=4*3.14 * r^2. Thus the area varies as the square of the radius. If the surface area is increased by a factor of 4, then the radius will have to increase by the square root of 4 which is 2.
