Question

the height of right circular cone is 16 cm and its base radius is 12cm. find tsa an volume

Answer 1

Answer:given

Height -16

Radius -12

Volume of cone -1÷3 πr2h

1÷3 *22÷7 (12)(12) *16

Ans- 2413.7

Step-by-step explanation:

Answer 2

Height (h) of cone = 16cm

Radius (r) of cone = 12cm 

let the Slant height of cone = l

l = √h^2 + r^2

l = √16^2 + 12^2

l = 20Cm.

Total surface area of cone = π r (l + r)

= π × 12 ( 20 + 12)

= 384 π cm2

Volume of cone = 1 / 3 π r^2 h

1 / 3 π × 12 × 12 × 16

= 768 π cm3
