Answer 2

Dear Student,

◆ Answer -

Area of Canvas required = 23.1 m^2.

● Explanation -

# Given -

r = 2.1 m

h = 2.8 m

# Solution -

Slant height of cone is -

l = √(r^2 + h^2)

l = √(2.1^2 + 2.8^2)

l = √(4.41 + 7.84)

l = √12.25

l = 3.5 m

Canvas required will be equal to curved surface area of the cone.

CSA = π × r × l

CSA = 22/7 × 2.1 × 3.5

CSA = 23.1 m^2

Hence, the area of Canvas required is 23.1 m^2.

Thanks dear. Hope this helps you..
