WebThe formula for the area of a cylinder is: A = 2πr (h + r) sq.unit Where r is the radius and h is the height of the cylinder. What is the formula for the volume of a cylinder? The formula for the volume of a cylinder is … WebThe area of the rectangle is the width times height. The width is the height h of the cylinder, and the length is the distance around the end circles. This is the circumference of the circle and is 2πr. Thus the rectangle's area is 2πr × h. Combining these parts we …
