(3cm)2 x pi = 28.274 cm2
Use this formula: A = PI(r)2
Area of circle of radius 3cm is 3 x 3 x pi ie 9pi sqcm, approx 28.26cm2
pi*1.52 = 7.069 square cm rounded to 3 dp
54 cm2
29.76
A = 28.27cm2
Using 3.14 as Pi the area of circle is: 0
Using 3.14 as Pi the area of circle is: 28.259999999999998
(3cm)2 x pi = 28.274 cm2
The area of a 3 cm circle is: 7.069 square cm
Pi x 3cm x 3cm= Area
Use this formula: A = PI(r)2
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)
Area of circle of radius 3cm is 3 x 3 x pi ie 9pi sqcm, approx 28.26cm2
It is pi*r^2 = 9*pi = 28.2743, approx.
pi*1.52 = 7.069 square cm rounded to 3 dp
