Area of a circle when radius is 3cm?
(3cm)2 x pi = 28.274 cm2
What is the answer in centimeter squared the radius of 3cm?
Area of circle of radius 3cm is 3 x 3 x pi ie 9pi sqcm, approx 28.26cm2
What is the diameter of a circle with a 3cm radius?
The diameter is six cm.
What is the exact area of a circle whos diameter is 6 cm?
There is no way to find the exact area of a circle. The formula for the area is Pi times the radius squared. But Pi is an irrational number -- that is, no matter how many numbers you write it out to, you could always write it further. Since there is no exact value of Pi there can be no exact value of the area based on the diameter. The radius is half that of a diameter. Therefore, if you know the diameter you know the radius. In this case the radius is 3cm and the area of the circle = pi * 32 So the answer is roughly
What is the suface are for a cylinder with a 7cm radius and 3cm height?
A cylinder with a 7cm radius and 3cm height has a total surface area of about 439.82cm2
What is the area of a circle if the radius is 3cm?
29.76
What is the area of a circle - radius 3cm?

Area of a circle when radius is 3cm?
(3cm)2 x pi = 28.274 cm2
What is The area of a circle of radius 3 cm?
Pi x 3cm x 3cm= Area
What is the answer in centimeter squared the radius of 3cm?
Area of circle of radius 3cm is 3 x 3 x pi ie 9pi sqcm, approx 28.26cm2
Area of a circle with a radius of 3cm?
Area of a circle = pi x radius2 The area of a circle with radius 3 cm = pi x 32 = 28.27433388 = 28.3 cm2 (1 decimal place)
What is the area of a circle with radius 3cm?
Area = pi x (radius^2) so 3.14...(3^2) = 28.274333882308139146163790449516 cm²
What is the answer of the area of a circle with a radius of 3cm?
It is pi*r^2 = 9*pi = 28.2743, approx.
