Diameter of the base of a cone is 10.5 cm and it's slant height is 10 ...
diameter = 10.5 cm
so, radius = 10.5/2 = 5.25 cm
slant heright (l) = 10 cm
we know that the curved surface area of a cone is pi*r*l
so the CSA of the cone = 22/7 * 5.25 * 10
= 165 cm^2
So the CSA of the cone is 165 cm^2

Diameter of the base of a cone is 10.5 cm and it's slant height is 10 ...
Given:
- Diameter of the base of the cone = 10.5 cm
- Slant height of the cone = 10 cm
To find:
- Curved surface area of the cone
Formula:
The formula to calculate the curved surface area (CSA) of a cone is:
CSA = πrl
where π is a mathematical constant approximately equal to 3.14, r is the radius of the base, and l is the slant height.
Calculation:
1. Radius of the base:
The diameter of the base is given as 10.5 cm. The radius is half the diameter, so the radius (r) = 10.5 cm / 2 = 5.25 cm.
2. Curved surface area:
Using the formula, CSA = πrl, we substitute the values:
CSA = 3.14 * 5.25 cm * 10 cm
Calculating the product:
CSA = 165.375 cm²
Answer:
The curved surface area of the cone is 165.375 cm².
