Question 1 Report
A cylinder, opened at one end, has a radius of 3.5cm and height 8cm. calculate the total surface area
Answer Details
The surface area of an open-top cylinder = πr(r + 2h),
where 'r' is the radius and 'h' is the height of the cylinder.
= 227 * 3.5 (3.5 + 2 * 8)
= 11 (3.5 + 16) → 11 (19.5)
= 214.5cm2
