A lawn sprinkler waters Kara's yard in a circular motion. The lawn sprinkler can water grass within a 7 foot radius. What is
the area of the yard that is watered by the sprinkler?

A. 43.98 ft
B. 87.96 ft
C. 153.94 ft
D. 615.75 ft

NEED HELP ASAP PLEASE, check the picture

option A

is the correct answer

Step-by-step explanation:

Wet grass forms a circular region of radius r=7 m.

∴ Length of the outer edge of wet grass(Perimeter) =2πr=2×

7

22

×7 m=44 m.

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

step-by-step explanation:

one day the were 5 ducks, and their king told them to multiply their kingdom. so each went their own seperate way and met 4 other ducks on their journey.

when the ducks returned to their kingdom, it was discovered that there were 5 groups of 5 ducks. when the kind counted the number of ducks in total (including the ones he sent out earlier) he counted 25.

therefore 5 times 5 is 25.

the end. : )
