Question

A lawnmower takes 750 complete revolutions to cut grass on a field. Calculate the area of the field if the diameter of the lawnmower is 84 cm and length is 1 m. *​

Answer 1

Step-by-step explanation:

THE lawnmower is in circle shape because in question the diameter is mentioned.

• THE Volume of circle is 5544cm²

The lawnmower takes750 revolution.

so,the area of the field is=750×5544=158,00.

Answer 2

Given ,

length of lawnmower = $1m = 100cm$

Its circumference = $\pi \times d = 227 \times 84 \\ = 264cm$

length of filed will be = $264 \times 750 \\ = 198000cm$

Here , the width of filed = length of the lawnmower i.e

$100cm$

so ,

area of filed =

$198000 \times 100 \\ = 19800000cm ^{2}$

or

$1980m {}^{2}$
