Question

A heap of rice is in a form of a cone whose radius is 7cm and height 24m
If the rice heap is to be covered by a canvas
Find the area of canvas
​

Answer 1

Step-by-step explanation:

first we have to find the CSA of the cone :-

$\pi \: rl$

${l}^{2} = \sqrt{} {r}^{2} + {h}^{2}$

l^2= 49+576

l^2= 625

l=

$\sqrt{625}$

l= 25

CSA of cone = πrl

22/7× 700×25

55000cm

after that we have to find the area of the canvas
