Question

the radius and the lateral surface area of a right circular cone are 8 cm and 10 cm square respectively find its slant height

Answer 1

The slant height is 0.397 cm.

Step-by-step explanation:

Given : The radius and the lateral surface area of a right circular cone are 8 cm and 10 cm square respectively.

To find : Its slant height ?

Solution :

The lateral surface area of a right circular cone is $LSA=\pi r l$

Where, r is the radius r=8 cm

l is the slant height

LSA is the lateral surface area LSA=10 cm²

Substitute the values in the formula,

$10=\frac{22}{7}\times 8\times l$

$l=\frac{10\times 7}{22\times 8}$

$l=0.397$

Therefore, the slant height is 0.397 cm.
