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.
What is the area of a circle with a radius of 16cm?

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.

A circle has a radius of 4 cm suppose you copy the circle using a size factor of 150 percent what will be the radius diameter circumference and area of the image?
Radius150% = x2.5So 4*2.5 = 1010cm is the new radiusAreaArea(cm2) = Pi(r)2Area(cm2) = Pi(10)2Area(cm2) = Pi(100)Area(cm2) = 314.1592654...= 314.16
