Question

6. The total surface area of a right cone is 1,760 cmand the radius of its base is 14 cm. Find the
following for the cone.
(a) height
​

Answer 1

Answer:

Answer:

Height of right circular cone = 21.9 cm

Step-by-step explanation:

Given that:

The total surface area of a right circular cone is 1,760 cm²

The radius of its base is 14 cm.

To Find:

The height of the right circular cone.

Formula used:

T.S.A = πr(r + l) sq. unit

Where,

T.S.A = Total surface area of right circular cone.

r = Radius of right circular cone.

l = Slant height of right circular cone.

π = 22/7

Finding the slant height of right circular cone:

→ 1760 = 22/7 × 14 × (14 + l)

→ 1760 = 44 × (14 + l)
