Question

Find the lateral surface area of two pillars if height of the pillar 7 m and radius of the base is 1.4 m
​

Answer 1

Answer:

44m^2

Step-by-step explanation:

r = 1m

h. = 7m of a pillar

CSA of a cylinder = 2πrh

2 × 22/7 × 1 × 7

= 2× 22

= 44 m^2

Answer 2

Answer:

123.2m²

Step-by-step explanation:

LSA of Cylinder = 2πrh

2×22/7×1.4×7

=61.6

There are two pillars so 61.6×2 = 123.2m²
