Question

Each base of a cylinder has an area of 1,962.5 square centimeters. The cylinder's lateral area is 194.2 square centimeters. Find the total surface area of the cylinder, in square meters.

Answer 1

0.41192 square meter

Explanation:

The total surface area of a cylinder is made up of 2 bases and its lateral area. Mathematically, you may have used this calculation: 2 × 1962.5 + 194.2 = 4119.2 square centimeters. To convert this to square meters, you must divide by 10,000: 4119.2 ÷ 10,000 = 0.41192 square meter.

Answer 2

total surface area of the cylinder= 2*area of base+lateral area=
=2*1962.5 + 194.2 = 4119.2 cm²

1m=100 cm
1m² = (100 cm)²
1m²=10000cm²

4119.2 cm² *(1m²/10000 cm²)= 0.41192 m²
