Question

Please help me tomorrow is my exam

Answer 1

Hey mate!

Height of cylinder = 15 cm.

Radius of cylinder = 7 cm.

Curved surface area = 2 π r h

$2 \times \frac{22}{ \cancel7} \times \cancel7 \times 15 \\ \\ = > 2 \times 22 \times 15 \\ \\ = > 44 \times 15 \\ \\ = > \bold{660 \: \: cm {}^{2} }$

Total surface area = 2 π r ( r + h )

$2 \times \frac{22}{ \cancel7} \times \cancel7(7 + 15) \\ \\ = > 2 \times 22 \times 22 \\ \\ = > \bold{968 \: \: cm {}^{2} }$


Thanks for the question!

Answer 2

hey here is your answer ✍✍✍✍.....

Radius of the cylinder = 7cm
Height of the cylinder = 15 cm
therefore , CSA - 2πrh
→ 2 × 22/7 ×7×15
→ 660 cm²
Now, total surface area= 2πr(r+h)
→ 2× 22/7 ×7(7+15)
→ 968 cm²

Hope it will be help for u
