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.

How do you calculate cross sectional area for steel bars?

Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.

What is the area of a circle with the radius of 12cm?

The area is pi*radius2 = 452 cm2, approx.
