Question

The total surface area of a solid cylinder having radius 24 cm and height 6 cm is:

A.

1440πcm21440π cm^2

B.

4440πcm24440π cm^2

C.

2440πcm22440π cm^2

D.

3440πcm23440π cm^2

Correct option is A

Given:

Radius of cylinder = 24cm

Height of cylinder = 6cm

Formula Used:

Total surface area of cylinder = 2πr(h+r)2\pi r(h+r)​​

Solution:

Total surface area = 2π(24)(6+24)2 \pi (24)(6+24)​​

=2×π×24×30= 2 \times \pi \times24 \times 30​​

=1440πcm2= 1440\pi cm^2​​
