Question

· Find the total surface area of a closed cylindrical drum if its diameter is 50 cm
and height is 45 cm.​

Answer 1

Answer:

$11000cm^2$

Step-by-step explanation:

Given:-

Diameter of the cylindrical drum $(d)$ = 50 cm

Radius of the cylindrical drum $(r)$ = $d$ ÷ 2

⇒ 50 ÷ 2

⇒ 25 cm

Height of the cylindrical drum $(h)$ = 45 cm

To find:-

Total surface area of the cylindrical drum

Solution:-

Total surface area of the cylindrical drum = $2\pi r(r+h)$

⇒ $2(\frac{22}{7})25(25+45)$

⇒ $2(\frac{22}{7})(25)(70)$

⇒ $2(22)(25)(10)$

⇒ $(22)(50)(10)$

⇒ $(22)(500)$

⇒ $11000cm^2$

∴ The total surface area of the cylindrical drum = $11000cm^2$.
