Answer:
heyyya mate!!
Step-by-step explanation:
Given:
The volume of cylinder, V = 44817 cm^3
Height of cylinder, h = 7cm
To find:
- Total surface area
- Lateral surface area
Solution:
LSA of cylinder = 2 pie r h
TSA of cylinder = 2 pie r ( h + r)
Volume = 44817
pie r^2 h = 44817
r^2 = 44817/7 × 7/22
r^2 = 2037.1
r = 45.13 cm
LSA = 2 ×22/7 × 45.13× 7
= 1985.72 cm^2
TSA = 2 × 22/7 × 45.13 ( 7 + 45.13)
= 2 ×22/7 × 45.13( 52.13)
= 14.787cm^2
The LSA and TSA of cylinder are 1985.72cm^2
and 14.787cm^2
