Question

Find Diameter and Volume of cyliner whose radius = 5cm and height = 10cm

Answer 1

Step-by-step explanation:

Given

The Radius of a solid cylinder (r)=5cm

Height (h)=10cm

Hence

Total surface area =2πrh+2πr  

2

 

=2πr(h+r)

=2π×5(10+5)

=π×10×15

=150πcm  

Answer 2

Answer:

Given,

   Radius of cylinder (r) = 5cm

   Height of cylinder (h) = 10cm

Diameter of cylinder = 2 x radius = 2 x 5cm = 10cm

Volume of cylinder = πr³ = $\frac{22}{7}$ x 5³ = $\frac{22}{7}$ x 125 = $\frac{2750}{7}$ = 392.857cm ³
