What is the area of a piston with diameter 6 cm?
What will be an ideal response?
The area of the piston is found by using the formula pR2. For example, a piston with a diameter of 6 cm has a radius of 3 cm.
Area of a circle = pR2 = 3.1416 x (3)2 = 3.1416 x 9 = 28.314 square cm
The area of the piston, then, is 28.314 cm2.
