circumference of the base=176
176=2πr
176=2×22/7×r
176×7/2×22=r
8×7/2=r
r= 56/2
r= 28
L.S.A.of cylinder= 2πrh
= 2×22/7×28×1
=2×22×4
=176

Answer:
1.76 m²
Step-by-step explanation:
Step-by-step explanation:
Circumference = 2 π R
176 = 2 π R
176 = 2 (22/7) R
Therefore, R = 28 cm
Height = 1 m
Lateral surface area = 2 π R x Height
2 π R = 176 cm = 176/100 m
= (176/100) * 1
= 1.76 m²
