Question

if radius and height of cone is 7cm and 24cm then find the csa​

Answer 1

Answer:

Given:

THE RADIUS AND HEIGHT OF A RIGHT CIRCULAR SOLID CONE ARE 7 CM AND 24 CM RESPECTIVELY

To find:

curved surface area and

total surface area of the cone.

Explanation:

Dimensions of a cone:

Radius (r) = 7 cm

Height (h) = 24 cm

Let the slant height = l cm

i)

=> l² = 7²+(24)²

= 49+576

= 625

l = √625

=> l = √25²

=> l = 25 cm

= (22/7) × 7 × 25

= 22×25

= 550 cm²

iii)

=(22/7)×7×(25+7)

= 22×32

= 704 cm²

Therefore,

CSA of a cone = 550 cm²

TSA of a cone = 704 cm²

Step-by-step explanation:

Answer 2

Answer:Dimensions of a cone:

Radius (r) = 7 cm

Height (h) = 24 cm

Let the slant height = l cm
