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 a radius 4.4cm?
Area of circle = pi * radius squared A = pi(4.4 cm)^2 = 60.8 centimeters squared ( call it 61 cm^2 )
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 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 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?

What is the answer of pi squared?
pi squared = approximately 9.8696044
What is the result when pi is squared or cubed?
pi squared is 9.869604401... pi cubed is 31.00627668
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)
