Answer:
35.35 square meters.
Step-by-step explanation:
The platform around a circular well is also circular.
It will be in the shape of a ring, with inner radius as 3m and outer radius is 3 + 1.5 = 4.5m. (1.5 meters is the width of the platform)
Hence it is given that
Inner radius = r = 3m
Outer Radius = R = 4.5m.
Area of the platform = π(R² - r²)
Substituting the values, we get
= 22(4.5² - 3²)/7
= 22(11.25)/7
= 35.35 square meters.
