Question:
Explanation:
Stated:
To Attain:
We know that,
Let us assume:
Solution :
⟹ 2 × ²²/₇ × 7 × 15
⟹ 660 cm²
⟹ 2 × ²²/₇ × 7 ×( 15 + 7)
⟹ 2 × 22 × 22
⟹ 968 cm²
Therefore:
Thank you for asking this question

Given :-
Solution :-
☆ 2 × 22/7 × 7 × 15
☆ ( 2 × 22 × 15 ) cm².
♛ Curved surface area of cylinder = 660 cm ♛
★Total surface area of cylinder = 2πr ( r + h )
❖ 2 × 22/7 × 7 ( 7 + 15 )
❖ ( 44 × 22 ) cm².
♛ Total surface area of cylinder = 968 cm² ♛
