What else can I help you with?
Why do you use the radius in the formula of finding the area of a circle?
Area of circle = pi*(radius)2
What is formula ofr finding area of a circle?
Area of a circle = pi*radius squared
What is the area of a circle if the radius is 18cm?
Using 3.14 as Pi the area of circle is: 1017.36
Formula for finding the area if you have radius?
Area of a circle = pi*radius2
What is the algorithm for finding the area of a circle?
Find the radiusMultiply pi by the square of the radius.
What is the equation for finding area in a circle?
It's radius x radius x pi.
How can you determine the area of a circle by using the radius squared and without finding the radius?
The area of a circle is pi * radius2. If you already have the radius squared, you just have to multiply that by pi.
What is Pi R Squared?
The formula for the area of a circle is πr^2, where π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. So, "pi r squared" refers to the area of a circle, calculated by multiplying π by the square of the radius. This formula is fundamental in geometry and mathematics for finding the area enclosed by a circle.
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 of finding the area of a circle?
Pi * R squared, where R is the radius of the circle in question
Area of circle radius 2.5?
The formula for finding the area of a circle is A= pi r2. Square the radius then multiply it by pi. For your instance, 2.5 squared is 6.25. 6.25 x pi= 19.634... The area of a circle with the radius of 2.5 is 19.634...
How is finding the area of a circle similar to finding the circumference of a circle?
They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2
