Question

A cylinder can be modeled as a rectangle rolled up around itself. The area of a rectangle is given by the formula A = bh . You want to find the area of the rectangle that surrounds the body of any given cylinder. The rectangle is the same height as the cylinder. The rectangle's base has the same length as the circumference of the circle that makes up the bottom and top of the cylinder. The circumference formula is C = 2pi*r Which of the following best builds a function for finding the area of a rectangle in a cylinder? (1 point) A = (2pi*tau)/h; A = 2pi*rh; A= hbar 2 pi tau .; A = b * h ^ 2
