Find the radius of the half cylinder. Simply divide the diameter by 2 (recall that the radius is equal to half the diameter). 2. Using the known values, solve for the area of the front semi-circle using the area of a semi-circle formula (1/2 x πr^2). 3. Next solve for the rectangular bottom area using the area of a rectangle formula (length x width). 4. Now we solve for the surface area of the cylindrical curved surface using the surface area of a cylinder formula (2πrh). Since this is a half cylinder we use the formula (1/2 x 2πrh). 5. Finally, add all of the areas together. _________________________________________________________ Social: YouTube:    / vividmath   Facebook:   / vividmath   Twitter:   / vividmath   _________________________________________________________ About VividMath: VividMath is an online math platform designed to help high school students boost their exam results.
