R = 500/9 times r squared
The formula for the volume of any sphere isVolume = ( 4/3 pi ) x (cube of the radius)
The formula for radius of a cone is radius is equals to square root of volume times 3, which is divided by height times pie. Pie refers to 22 divided by 7.
SA = 4pi62
volume = p*radius2*height make the radius the subject of the formula: radius = the square root of (volume/pi*height) radius = the square root of (2826/pi*36) radius = 4.998732446cm So the radius is 5cm to the nearest cm.
Yes it is, where r is the radius
well, technically since the formula for circumference is c=2pir, technically r=c/2pi (otherwise stated as radius equals circumference divided by two pi).
SA equals pi times the radius squared
The formula for the area of a circle is pi * radius squared. The circumference of a circle's formula is pi * diameter. NOTE: pi equals approx. 3.14
radius square mutiplied by pi.thus pi equals 22/7 or 3.143.
That is the formula for calculating the area of a circle with a 10 unit radius. The answer is 314 sq units.
The formula for the surface area of a circle is pi times the square of the radius. It is represented as A equals pi times r squared.
"Radius equals 0.9 meters" is not a question.
