Question

A tent is in a shape of
shape of a cylinder, surmounted
by
a conical top. If the
height
and diameter of the cylindrical part
2.1m and 4m_respectively
and the slant height of the top is 2.8 m. find the
area of the canvas used for makeup the tent.

​

Answer 1

Step-by-step explanation:

the class was good to hear from you soon

Answer 2

${\huge {\boxed{\bold{\boxed{\sf{\color{green}{answer}}}}}}}$

from the question, we know that

the diameter = d = 4 m

l = 2.8 m (slant height)

the radius of the cylinder is equal to the radius of the cylinder

so, r = 4/2 = 2 m

also, we know the height of the cylinder (h) is 2.1 m

so, the required surface area of the given tent = surface area of the cone (the top) + surface area of the cylinder(the base)

= πrl + 2πrh

= πr (l+2h)

now, substituting the values and solving it we get the value as 44 m^2

∴ the cost of the canvas at the rate of rs. 500 per m^2 for the tent will be

= surface area × cost/ m^2

= 44 × 500

so, rs. 22000 will be the total cost of the canvas

hope it's helpful.....:)
