Answer
Total Surface Area of the cylinder is 905.1 cm²
Explanation
Given
Height of the cylinder is 7 cm
Area of the base is 250 cm²
To Find
Total Surface Area of the cylinder?
Solition
[We shall first find the radius of the the base of the cylinder and then simply substituting them on formula will get us our Answer]
✭ Radius of the cylinder
➝ Area of circle = πr²
Area = 250 cm²
➝ 250 = πr²
➝ 250 = 22/7 × r²
➝ 250 × 7/22 = r²
➝ 79.5 = r²
➝ √79.5 = r
➝ Radius = 9 cm
✭ TSA of cylinder
➝ TSA of cylinder = 2πr(h+r)
➝ TSA = 2 × 22/7 × 9 (7+9)
➝ TSA = 44/7 × 9(16)
➝ TSA = 44/7 × 144
➝ TSA = 905.1 cm²
