Pi x 3cm x 3cm= Area
The surface area is 226.2cm2
The area of a circle if the radius is 9m 254.5m2
The radius of a circle with the area of 36 is 3.385
A circle with a radius of 10m has an area of 314.16 m2
29.76
A = 28.27cm2
Using 3.14 as Pi the area of circle is: 28.259999999999998
(3cm)2 x pi = 28.274 cm2
Pi x 3cm x 3cm= Area
Area of circle of radius 3cm is 3 x 3 x pi ie 9pi sqcm, approx 28.26cm2
Use this formula: A = PI(r)2
Area = pi x (radius^2) so 3.14...(3^2) = 28.274333882308139146163790449516 cm²
It is pi*r^2 = 9*pi = 28.2743, approx.
The perimeter of a circle is its circumference and it is: 2*pi*radius or pi*diameter
The diameter is six cm.
A cylinder with a 7cm radius and 3cm height has a total surface area of about 439.82cm2
