Answer: The area of the mirror is 113.14 sq. inches [approx.].
Step-by-step explanation: Given that a circular can till 375 ft² of land in 15 min.
We are to find the area of the mirror in square inches.
The AREA of a circle with radius 'r' units is given by

The diameter of the circular mirror is 12 inches, so the radius of the mirror will be

Therefore, the area of the circular mirror is
![A=\pi r^2=\frac{22}{7}\times 6^2=\dfrac{22\times 36}{7}=113.14~\textup{sq inches}~\textup{[approx.]}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2%3D%5Cfrac%7B22%7D%7B7%7D%5Ctimes%206%5E2%3D%5Cdfrac%7B22%5Ctimes%2036%7D%7B7%7D%3D113.14~%5Ctextup%7Bsq%20inches%7D~%5Ctextup%7B%5Bapprox.%5D%7D)
Thus, the area of the mirror is 113.14 sq. inches [approx.].

The absolute value of 13 is 13. The absolute value of a number is always positive.
Answer:
600 minutes
Step-by-step explanation:
The total rate of the Pump is gotten first
15 + 20 = total rates of 35 gallon per hour .
rate = volume/ time.
Volume = rate * time
21,000 = 35 * t
t = 21,000/35
t = 600 minutes.
To check the volume each pump will pump out.
pump A 15 * 100 = 9000 gallons
Pump B 20 * 600 = 12000 gallons.
12,000+9,000= 21,000 which gives the total gallons of the swimming pool back
