Its radius is: 8/2 = 4ft

25.12ft

The volume is Base x height; the Base area is the same as the formula for a circle - which is proportional to the square of the radius. For example, if you double the radius (or the diameter, or the circumference) of a circle, its area will quadruple.

Radius

Quadrupling the base radius will do that.

The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.

The area is 9.2376 square feet.

The surface area of this cylinder is 376.99ft2

The surface area is 377ft2

The answer depends on whether the 4 foot measure is the radius or the circumference.

The area of the pizza inceases as the square of the radius (or diameter). Assuming the thickness remains the same, then the volume also increases as the square of the radius. So, double radius implies quadruple area implies quadruple cost.

A round pool with a radius of 9 feet and a depth of 4 feet has a capacity of about 7,615 gallons of water.

Circumference=2Ï€r=2 xÏ€ x4â‰ˆ25.13

Most quantities can quadruple.

Quadruple means four-fold, or four times. I now have quadruple the money that I started with.

That is the correct spelling of the word "quadruple".

Half the mass means half the force. However half the Radius means quadruple the force. Meaning the force will be double then the force on earth, and so will the acceleration be.

does quadruple have any silver in it

Quadruple means 4 times

4ft*4ft*4ft=64 cubic feet

60 inches is bigger. 60in = 5ft 48in=4ft

4ft to inches is: 12x4= 48inches

carbons cannot have quadruple bonds.

yes its 4ft 1 in
