Question

Find the total surface area of a cylinder with base diameter 21m

‘ and height 24m​

Answer 1

Step-by-step explanation:

d = 21 m

r = 21 / 2 m

h = 24 m

total surface area =

$\pi \: r \: {h + r}$

22 × 21 / 7 × 2 ( 24 + 21/2)

11 × 3 ( 48+ 21/2)

33 × 69 / 2 m²

then calculate by yourself
