Why do you use the radius in the formula of finding the area of a circle?
Area of circle = pi*(radius)2
Formula for finding volume and area of sphere?
Volume = 4/3 * pi * radius * radius * radius Surface Area = 4 * pi * radius * radius
What is the formula for finding an area of a circle?
The area of a circle with a known radius can calculated using the following formula where r is the radius : A = Pi(r)2
What is the formula for finding the mass of a cylinder?
The formula for finding area or mass of a cylinder is pi x radius^2density=massxvolume
What is formula ofr finding area of a circle?
Area of a circle = pi*radius squared
What is the formula of finding the height of a cone?
It depends on what information you have: its radius and slant height, radius and volume, radius and surface area, surface area and volume, etc.
Formula for finding radius of a circle?
c=TT R Given the area, the radius = square root (area / Pi). Given the circumference, the radius = circumf/ 2Pi.
What is pr2?
It is the formula for finding the area of a circle which means: pi times radius squared
What is formula in finding the surface area of the cylinder?
2πrh, where 'r' is the radius and 'h' is the height.
What is pi times the radius sq?
pi*radius2 is the formula for finding the area of a circle.
What is the formula for finding the radius?
The formula for finding the radius of a circle is circumference divided by double of pi. If area is given instead of circumference, the radius may be found by dividing the area by pi, then finding the square root of the resultant quotient. It is also equal to half of the diameter, or the diameter divided by 2.
What does the formula Pi r2 mean?
It is the formula used in finding the area of a circle which is pi times radius squared
