What is the surface are of a sphere with radius 8?

The surface area of a sphere can be calculated with the formula: A = 4[pi]r2 Plug in r: A = 4[pi](8)2 And solve: A = 256[pi]


What is the area of a sphere with a radius of 8?

Surface area of sphere = Pi x diameter2 = Pi x (2r)2 = Pi x 256 (approximately 804.25 square units).

256 Pi. The area of a circle is equal to the radius square multiply by pi


What is the volume of a sphere with radius 4?

The formula is (4*pi/3)*r^3, so 256*pi/3 cubic units = 268.08 cubic units. {whatever units r is in}


What is the volume of a sphere of radius 4 meters?

The volume of a sphere is given by the formula V = 4/3(pi)R^3. So a sphere of radius 4 meters would have a volume of 4/3(pi)(4^3) = 256(pi)/3, or approximately 268 cubic meters.


What is the surface area of a cube with edges measuring 16 feet?

One side of the cube would have a surface area of 16 X 16, which is 256 sq. ft. And a cube has 6 sides, 6 X 256 = 1536 sq. ft.

What is the radius of a circle if it had a 90 degree sector and an area if 64pi?

From your question, we can't tell whether [ 64 pi ] is the area of the circleor the sector.The area of a circle is [ pi R2 ].If [ 64 pi ] is the area of the circle, then the radius is [ 8 ], and we don't careabout the sector.If [ 64 pi ] is the area of the sector, then the area of the full circle is [ 256 pi ](because the 90-degree sector is 1/4 of the circle), and the radius is [ 16 ].


What is the area of a circle with the radius of 16in?

256 x pi squinches 16 in x 16 in x 3.1416 = 804.25 in (rounded to 2 decimal places)
