A radius squared fits pi times into a circle (The area of a circle divided by pi is the radius squared).
Since area equals Pi times radius squared take and substitute what is known. 345 equals Pi times the radius squared. divide Pi into both sides for 109.8 equals the radius squared. Now take the square root of 109.8 to get an r of 10.47936 cm.
pi times the radius squared times the measure of the arc divided by 360
The area of the base of a cylinder = Pi times Radius squared. Diameter of a cylinder = 2 times Pi times Radius. To find the diameter derive the area of the base by Pi and then square root the answer. That will give you the value of the radius. Multiply that answer by 2 times Pi and you will have your answer.
pi times the radius squared pi r squared
(pi times radius squared) plus (pi times radius times slant).
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
The area of a circle is pi times (radius squared) Thus if radius is one inch then area is (pi) times (1) times (1) = pi = 3.1416 inches squared
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
Pi times radius squared.
That is correct because the surface area of a sphere is: 4*pi*radius squared
Area of a circle: pi times radius squared Circumference of a circle: 2 times pi times radius or diameter times pi
The answer is Pi times radius squared. Although you can't know anymore since you don't give what the radius is. Although, Pi can be simply referred to as 3.14
A= Area of the circle¶= Pi (About 3.14)r= Radius squared (Radius times radius)3.14 * Radius squared
The area of a circle is: pi times radius squared
perimeter (circumference): diameter times pi (3.14) area: radius times radius times pi (3.14) Area = pi*radius squared Circumference = 2*pi*radius or pi*diameter
