The radius of the area the sprinkler has watered is 8.06 yards.
<h3>What is Rotation ?</h3>
Rotation is spinning around a fixed point with a fixed radius in circular motions.
It is given that a sprinkler rotates 360 degree
The area watered is 204 sq. yards
Radius = ?
A sprinkler rotates in circle
Therefore the area of the circle = π r²
204 = π r²
204 * 7 /22 = r²
r² = 64.91
r = 8.06 yards
Therefore the radius of the area the sprinkler has watered is 8.06 yards.

I sent you a photo so u understand how
- Product Rule of Radicals: √ab = √a × √b
So firstly, factor out i (i = √-1):
10i√80
Next, apply the product rule of radicals and simplify the radical as such:
√80 = √10 × √8 = √5 × √2 × √4 × √2 = 2 × 2 × √5 = 4√5
10i × 4√5 = 40i√5
<u>Your final answer is 40i√5.</u>
