Question

the radius of the base of a cone is 5cm and its height is 12cm find :-
1) curved surface area
2) volume of cone ​

Answer 1

Answer:

1))204.28 (2)314.28

Step-by-step explanation:

l=

13 so curved s.a =22/7×5×13=204.8 volume =1/3×22/7×5×5×12=314.28

Answer 2

Answer:

Step-by-step explanation:

→ Mark as brainliest answer.

→ Base of cone =  5 cm

→ Height of cone = 12 cm

→ Formula of curved surface area of cone = πrl

→ 22/7 × 5/1 × 12/1

→ 1320/7

→ 188.5 cm²

→ Formula of volume of cone = 1/3 πr²h

→ 1/3 × 22/7 × 5/1 × 5/1 × 12/1

→ 6600/21

→ 314.28 cm³
