of height 15 cm and diameter 4 cm? What will be the
total cost of the sheet required if the rate of the sheet is
20 per 100 cm?? (Use t = 3.14.)​

Answer 1

Answer:

kindly see the answer below....

Step-by-step explanation:

Here, given that

height = 15 cm

radius = 2 cm

rate of the sheet = Rs 20/100 cm

therefore,

sheet required to make one open cylinder is

$= 2\pi \times 2 \times 15 \: cm$

then, sheet required to make 50 such cylinders are

$= 50 \times 2\pi \times 2 \times 15 \: cm$

then,

cost of the total sheets

$= 20 \times 2\pi \times 30 \times 50$

$= 188400 \: rupees$

Now,

9420 cm sheet is required to make 50 such open cylinder..

the total cost required is Rs 188400..

thanks a lot..
