What is the area of a circle of its circumference is 3.2π cm?
Circumference = 3.2pi cm => diameter = 3.2 cm => radius = 1.6 cm.Therefore, area = pi*r2 = 1.62*pi = 2.56*pi cm2 = 8.04 cm2 approx.Circumference = 3.2pi cm => diameter = 3.2 cm => radius = 1.6 cm.Therefore, area = pi*r2 = 1.62*pi = 2.56*pi cm2 = 8.04 cm2 approx.Circumference = 3.2pi cm => diameter = 3.2 cm => radius = 1.6 cm.Therefore, area = pi*r2 = 1.62*pi = 2.56*pi cm2 = 8.04 cm2 approx.Circumference = 3.2pi cm => diameter = 3.2 cm => radius = 1.6 cm.Therefore, area = pi*r2 = 1.62*pi = 2.56*pi cm2 = 8.04 cm2 approx.
If the diameter of a circle 20 cm is tripled what will the area be?

What is the area of a rhombus with the diagonals 14 cm and 8 cm?
The area is 56 cm2
How do you calculate cm2?
To calculate area, or cm2, the length and width must be multiplied. For example, a length of 2 cm and a width of 3 cm equals an area of 6 cm.
