Question

Find width w of the parallelogram so that area is equal to 600 square feet

Answer 1

The total surface area A of a cylinder is given by the sum of the area of the lateral surface plus the areas of the base and bottom of the container.  

A = 2 × radius × π × height + π × radius2 + π × radius2

= 2 × 5 × π × 34 + π × 52 + π × 52

= 340 π + 25 π + 25 π = 390 π square centimeters  

= 1224.6 square centimeters (using π = 3.14)  

The volume V of the given cylinder is equal to  

V = π × radius2 × height  

= π × 25 × 34 = 850 π cubic centimeters  

= 2669 cubic centimeters (using π = 3.14)
