The curved surface area of a cylinder with a height of 8cm and diameter of 10cm is 251.33cm2
It is a right angle triangle and its largest angle is 90 degrees
The formula for the surface area of a cylinder is 2πrh + 2πr^2, where r is the radius and h is the height. Plugging in the values given (r=8cm, h=10cm), we get 2π(8)(10) + 2π(8)^2 = 160π + 128π = 288π cm^2. Therefore, the surface area of the cylinder is 288π square centimeters.
The area of triangle is : 24.0
It is sqrt(62 + 102 + 82) = sqrt(200) = 60.53 cm (approx).
