a circular well has radius 3m if a platform of uniform width of 1.5 m

1.	a circular well has radius 3m if a platform of uniform width of 1.5 m is laid around it, find the area of the platform?
Answer» 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.

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.
