What is the area of a circle with radius of 9?
area of a circle = pi r squared = pi x (9 squared) = 254.47 to 2 decimal places
What is the area of a circular region whose diameter is 12 centimeters?
the area of a circle is pi times the radius squared. The diameter is 12, so the radius is 6 (half of the diameter). Therefore, the area is pi times 6 squared, which is 36 pi square centimeters. Also, if you want the answer in decimal, it's 113.09733552923255658465516179806 square centimeters.
What is the area of a circle with radius 28 centimeters?
Using 3.14 as Pi the area of circle is: 2461.76
What is the area of a circle with a diameter of 6 in?
The formula for area of a circle is: A = (pi)*r^2 If the diameter of a circle is 6 then the circle's radius is 3. So, A = (pi)*(3)^2 A= 9*(pi) inches squared or A = 28.26 inches squared (rounded)
What is pi squared to the one half power?
it is pi..... wait no it isnt.....pi squared to the one half power is not pi...
What is the area of a circle with radius of 9?

What is the surface area of a pringles can?
Entire surface area of a cylinder = (2*pi*radius2)+(pi*diameter*height)
How do you find circumference with 3 inches?
the formula is pi times r squared pi = 3.14 r = 3 3 squared = 9 so its 3.14 times 9
What is the volume of a cylinder with a radius of 9 cm and a height of 8 cm?
648pi. (pi = 3.14159...)Area of a circle = (pi) x (radius squared)= (pi)(9 squared) = (pi)81.Area of a cylinder = area of circle x height.= (pi)81 x 8= 648(pi)
What is the circumference of a circle that the radius is 9 centimeters?
circumference = 2*pi*9

What is the result when pi is squared or cubed?
pi squared is 9.869604401... pi cubed is 31.00627668
What is the difference between 2 centimeters and 2 centimeters squared?
2 centimeters is just 2 centimeters, and 2 centimeters squared is 4 centimeters. 2 centimeters x 2 centimeters = 4 centimeters squared = times 2
How do you work out the mass of a cylinder?
Area of cylinder base = pi x Radius squared (πr2) Radius is in centimeters (cm) Area is in centimeters squared (cm2) ---- Volume = Area x Height Area is in centimeters squared (cm2) Height is in centimeters (cm) Volume is in centimeters cubed (cm3) ---- Mass = Volume x Density Density is in grams centimeter cubed (g/cm3) Volume is in centimeters cubed (cm3) Mass is in grams (g)
