Find the curved surface area of a cone of radius 3cm and slant height 7cm (\(take \pi = \frac{22}{7}\)
Question 1 Report
Find the curved surface area of a cone of radius 3cm and slant height 7cm (\(take \pi = \frac{22}{7}\)
Answer Details
The curved surface area of a cone can be calculated using the formula:
`Curved surface area = πrl`
where r is the radius of the base, l is the slant height, and π is the constant pi.
In this case, the radius is given as 3cm, and the slant height is given as 7cm.
So, the curved surface area of the cone is:
`Curved surface area = πrl`
`Curved surface area = (22/7) x 3 x 7`
`Curved surface area = 66 cm^2`
Therefore, the curved surface area of the given cone is 66 cm^2. Answer is the correct answer.
