What is the total surface area of a cylinder with a radius of 7 m and a height of 8 m?(a) 609.4 m^2(b) 659.4 m^2(c) 650.4 m^2(d) 689.4 m^2This question was addressed to me in exam.My question is based upon Surface Area and Volume of Different Solid Shapes topic in division Surface Area and Volumes of Mathematics – Class 10

Answer»

Right option is (b) 659.4 m^2

The BEST explanation: Total surface AREA of a cylinder = 2πr(h + R)

= 2 × \(\frac {22}{7}\) × 7 × (8 + 7)

= 659.4 m^2
