Question

Find the total surface area and volume of the following cylinders,given the radius and height.
1.r=10.5cm,h=15cm

Answer 1

Answer:

TSA of cylinders = 1681.5cm

Volume of cylinder = 5195.41

Step by step explanation :

Given,

r = 10.5cm

h = 15cm

TSA of cylinders = 2π r h + 2π r²

= 2 × 22/7 × 10.5 × 15 + 2 ×22/7 × 10.5 × 10.5

= 989.1 + 692.37 ( or 692.4 when estimated)

= 1681.5 cm

Volume of the cylinders = πr2h

= 22/7 × 10.5 × 10.5 × 15

= 5195.41 cm approx.
