Question

A water sprinkler in a lawn sprays water as far as 70 m in all directions. Find the length of the outer edge of wet grass.​

Answer 1

Answer:

440m

Step-by-step explanation:

Wet grass forms a circular region of radius r=70 m.

∴  Length of the outer edge of wet grass(Perimeter) =2πr = 2*22/7*70m

= 440m

Hope this answer helped you.

Answer 2

Answer:

It sprays water in all directions,i.e.,70 m.

This is only possible if it sprays in a circular region.

Thus, the radius of the circle is 70 m.

Circumference of circle = 2πr = 2×22/7×70 = 440 m

.°. The length of the outer edge of wet grass is 440m.

Very glad to help you.
