a tent is cylinder to a height of 4.8 m and concial above it radius of bade 4.5 total length of the tent is 10.8m find the canvas required for the tent in sqare metres
Answers
Answer:
220,63 m²
Step-by-step explanation:
cylinder cone
H = 4.8m r = 4.5m l ² = 4 .5² + 6²
R = 4.5m h = 10.8 - 4.8 = 20.25 +36 = 56.25
= 6 m ∴ l = √56.25 = 7.5m
Canvas required for tent = CSA of a cylinder + CSA of cone
= 2πRH + π rl
= 2 x 22/7 x 4.5 x 4.8 + 22/7 x 4.5 x 6
= 135 .77 + 84.86
= 220.63 m²
Answer:
canvas required for the tent = 241.79m²
