Question

The radius of a circular pond is 28m A path of 1.4m width is present around it . Find the area of path

Answer 1

Answer:

252.56 sq.m

Step-by-step explanation

R = 28 + 1.4 = 29.4 m

Area of path = πR² - 4²

= π(R² - r²)

= π(29.4² - 28²)

= 3.14 x 80.36 = 252.56 sq.m

Answer 2

Answer:

Hope it helps you

Step-by-step explanation:

Radius of circular pond (r) = 28 m Radius of circular pond including path (R) = 28 + 1.4 = 29.4 m Area of path = πR2 – 42 = π(R2 – r2) = π(29.42 – 282) = 22/7(864.36 – 784) = 22/7 x 80.36 = 252.56 sq. mRead more on Sarthaks.com - https://www.sarthaks.com/837130/the-radius-circular-pond-28-meter-path-of-meter-width-is-present-around-it-find-the-area-path
