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 the radius of A equals 121 pi cm squared?
Remember the Area of a Circle equal 'pi' multiplied to radius squared. Algebraically. A = pi r^(2) Hence r^(2) = A/pi r = sqrt(A/pi) Substituting r = sqrt( 121 pi / pi ) Cancel down by 'pi' r = sqrt(121) r = 11 cm
What is formula for pi r squared?
The area of a circle = pi*r2
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 get area of a circle?
A=pi(r)squared
What is the solution to pi plus the squared hypotenuse of a 90 degree right triangle?
It is not possible to answer the question because the squared hypotenuse can have any positive value.
What is 2 pie r sqaured?
Pi r squared is the formula for the area of a circle. 2 pi r squared is twice that.
How do you find the are of the base of a cylinder?
SA=2(pi times r squared) + h(pi 2 r) or (easier way) 2 pi r squared + 2 pi r h
How do you find out the area of a circle?
pi times the radius squared pi r squared
What is Pi times r squared if r is sixty eight?
that is 14,519.4 squared
What is pie r 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
Is 2Pi r the same as Pi r squared?
No. 2Pi r is equal to Pi d, though.
A vertex is a what with how many dimensions?
A vertex is a quadralateral edge, with the hypotenuse of pi 8 squared. it has 12 dimensions.
