Question

The radius and slant height of a cone are in the ratio of 2: 7. If its curved surface area is 704 cm^2. find its radius, slant height and height

Answer 1

Answer:

The ratio of the radius and height of the cone is 2 : 7.

Let the radius of the cone be 2x and the height be 7x

Step-by-step explanation:

So,

Curved surface area of the cone = πrl

792 = 22/7*2x*7x

x² = (792*7)/(22*2*7)

x² = 18

x = √18

x = 4.24 cm

So, the radius of the cone = 4 × 4.24 = 16.96cm

or

x=√18 then

the radius of the cone = 4 x √18= 4√18
