How do you find the radius of a circle when the area is given?
-- Take the formula for the area of the circle in terms of the radius . . . A = (pi) R2-- Solve that formula for 'R'. You'll then have a formula for the radius in terms of the area,which is exactly what you're looking for.
Radious formula for a cicrle?
It is not clear whether you want the formula of some aspect (area or circumference) of a circle when given its radius or a formula for its radius when given some characteristic measure of the circle.
What is the formula for area of the circle?
The formula for area of a circle is TTr2.This means that we multiply 3.14(the rounded off nunber for pi) by the radius and radius(3.14xradiusxradius).If the diameter is given,divide it by 2 to get the radius.
What is the area of a circle if the radius is 7 mm?
The formula for an area of a circle is the greek symbol "pi" times the radius squared. A = π * r2 r = radius π = 3.14 Now, your radius is given to you in millimeters. Generally answers are given in meters. 7 mm (millimeters) is equal to .007 m (meters).
Given a sphere with radius r the formula 4r2 gives?
If you mean 4*pi*r^2 then it is the formula for finding the surface area of a sphere

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.
Radious formula for a cicrle?
It is not clear whether you want the formula of some aspect (area or circumference) of a circle when given its radius or a formula for its radius when given some characteristic measure of the circle.
A circle has radius r what is the formula for the area of the circle?
For a circle or radius r, the area is given by: area = {pi}r2 (ie pi times the radius squared)
What is the formula for area of the circle?
The formula for area of a circle is TTr2.This means that we multiply 3.14(the rounded off nunber for pi) by the radius and radius(3.14xradiusxradius).If the diameter is given,divide it by 2 to get the radius.
What is the formula to find the area of a circle with the radius given?
A = pi x radius squared where pi = 3.14
What is the area of a 6.2 radius circle?
The area of a circle is given by the formula A = πr^2, where A represents the area and r represents the radius. Plugging in the given radius of 6.2 into the formula, we have A = π(6.2)^2. Evaluating this expression gives an area of approximately 120.79 square units.
What is the formula to find a area of a circle when given radius?
A = pi x radius2
What is the formula to be used if the diameter is given?
The answer depends on the formula for what: the radius, circumference, length of an arc, area, area of sector, area of segment: each one has a different formula.
What is the formula to find the radius given the are of a circle?
it is square root of the area divided by pi
What is the formula in finding the height of a cylinder?
The answer depends on what information you are given: volume and radius or diameter, or surface area and radius, etc.
What is the answer for the hemisphere?
The answer for the hemisphere is half the volume of a sphere, which is given by the formula (2/3)πr³, where r is the radius. The surface area of a hemisphere is half the surface area of a sphere, given by the formula 2πr².
