In a circle a 90 degrees sector has an area of 225 pie in squared What is the radius of the circle?
area = 225 pi = pi R squared/4 R = square root 900 = 30 in
What is the radius of the area 345cm2?
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.
How do you find the radius of a circle if the area is 108?
The radius will be about 5.87 (units). The formula for the area is A = (pi) r2 where pi is about 3.1416 and r is the radius (squared) 108 = 3.1416 (r2) 34.38 = r2 r = about 5.87
What is the radius of a circle with circumference of 8 inches?
C = 2*pi*r 8 = 2*pi*r 4 = pi*r r = 4/pi
What is the formula for the area of the circle?
r2*pi=A π ● r² or pi times the radius squared If you are given the diameter just divide that by 2 giving you the radius. After that square the radius (multiply by it by itself). Then multiply that answer by 3.14 or pi. Area of a circle = pi*radius2
Do you multiply the radius or the diameter of pi?
The raduis.It's pi, r squared. the r stands for radius!
How do you find out the area of a circle?
pi times the radius squared pi r squared
How you get the area of a circle?
A= Area of the circle¶= Pi (About 3.14)r= Radius squared (Radius times radius)3.14 * Radius squared
What is pi r r?
Pi times r times r or Pi r squared is the formula for finding the area of a circle where r is the radius
In a circle a 90 degrees sector has an area of 225 pie in squared What is the radius of the circle?
area = 225 pi = pi R squared/4 R = square root 900 = 30 in
If the area of a circle is 25 square units what is the radius of the circle?
area equals pi r squared therefor r squared equals area over pi. Now find square root of r squared and you have "R" (radius) = 2.821
How do you work out pi r squared?
That is the formula for the area of a circle; r refers to the radius, and pi is approximately 3.14. r squared means that you multiply r x r.
What is pie r squared?
"Pi R Squared" refers to the formula for the area of a circle. A = (pi)r2 (3.1416 times the square of the radius)
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 relationship between the area of a circle and its radius squared?
The area of a circle is defined by the equation A = πr^2 where π = pi (3.14...) A = Area r^2 = radius squared So, the radius of a circle squared multiplied by pi equals the area.
What is Pi R Squared?
The formula to get the area of a circle ("R" being the radius of the circle). Radius means the distance from the center of the circle to the edge.It means pi times radius squared which is the formula for finding the area of a circle.
What is the circumference of a circle with a 7 foot radius?
Circumference = pi x r squared: where pi = 3.14159 and r = radius (squared) Circumference = 3.14159 x 7 x 7= 153.938 feet
