Calculating square inches of a circle?
The area of a circle is easily found by multiplying its radius squared times the constant pi. If only the circumference is known, the radius is found by taking 1/2 of the circumference divided by pi.
What is found by mulitplying pi by the radius squared?
The area of a circle with the given radius.
How do you find volume for cylinders with 7cm?
The volume of any cylinder can be found by multiplying the value of Pi by the radius squared, then multiplying by the height. Since you didn't specify whether the 7cm measurement was the radius or diameter - you will have to do the calculations yourself based on the information in this answer !
How do you find the circumference and area with a radius of 15 inches?
The circumference is found by doubling the radius, and multiplying that number by the value of PI. The formula is Pi x 2rThe area is found by squaring the radius, then multiplying that number by the value of Pi. The formula is Pi x r2 The letter r in both cases represents the radius.
How do you determine the circular area of a lawn?
pi radius squared. (radius squared, then multiply by pi.)

What Pi used for?
Pi has many usages in mathematics some of which are:- Area of a circle = pi*radius squared Circumference of a circle = diameter*pi or 2*pi*radius Surface area of a sphere = 4*pi*radius squared Volume of a sphere = 4/3*pi*radius cubed Volume of a cone = 1/3*pi*radius squared*height The value of pi is found by dividing the circumference of a circle by its diameter
How do you determine the circular area of a lawn?
pi radius squared. (radius squared, then multiply by pi.)
What is the measure inside of the circle?
It is its square area which is found by pi*radius squared
What is the measure of the inside of a circle?
It is its square area which is found by pi*radius squared
What is the measure of the inside of the circle?
It is its square area which is found by pi*radius squared
What is the area of a circle when the radius is 6?
the area of a circle is found by the formula (pi)r^2 ...pi times the radius squared... so in this case, 36pi
What is An area of circle?
The area of a circle is the amount of space inside the circle. The area of a circle is calculated by multiplying pi(3.14159) by the radius squared.
How do you find the radius and diameter of a circle if you know the area?
The area of a circle is found by multiplying pi time the radius squared A = (pi) r2 So to find the radius, divide the area by pi and then take the square root to get the radius. The diameter is always exactly twice the radius. --- Example: Area = 100 A = (pi) r2 100 = (3.1416) r2 r2 is 100/3.1416 or about 31.83, and the square root is 5.64 r = 5.64 and D = 11.28
