Question

help me fast its urgent​

Answer 1

Answer:

Height =10cm

∴ circumference of base = length of rectangular sheet

2πr = 22

$so \: \: 2 \times \frac{22}{7} \times r = 22$

$r = \frac{7}{2}$

hence ,volume of cylinder =πr² h

$\frac{22}{7} \times \frac{7}{2 } \times \frac{7}{2} \times 10$

= 385cm³

Step-by-step explanation:

I hope that it will help you

Answer 2

Step-by-step explanation:

since since rectangular piece of paper of rolled along its length

2πr=22

r=22×7/2×22=3.5cm

height of cylinder=10

volume of cylinder=πr^2h

22/7×3.5×3.5×10

385cm^2
