Question

find the volume of a conical vessel having base radius 5 cm and slant height 13cm given as equal given Pi is equal to 3.14

Answer 1

Answer:

Step-by-step explanation:

We are given that radius,R = 5cm.

And Slant Height, L= 13 cm.

To find the height we have to find the use Pythagoras theorem , so

(L)^2 = (H)^2 + (R)^2

13^2 = (H)^2 + 5^2

(H)^2 = 13^2- 5^2

(H)^2 = 169 - 25

(H)^2 = 144

H = √144

H = 12 cm

Volume of cone = 1/3πR^2*H

=> 1/3* 3.14*(5)^2*12

=> 3.14*25*4

=> 3.14* 100

=> 314 cm cube

Volume of cone = 314 cm cube

Hope this helps you

All the best

Answer 2

Answer:

314

Step-by-step explanation:

• r=5
• l=13

• h=?

let ABC be a right triangle AC(l)=13 BC(r)=5 AB=h

AB^2=AC^2-BC^2

AB=12

• h=12

volume=1/3\pi r^2h

answer =314
