Answer:
112 in^2
Step-by-step explanation:
The equation to calculate the area of a circle is A=πr^2. We can solve for the radius of the circle by:
1) plugging in our known value, A=7. So 7=πr^2
2) dividing both sides by π.
7/π=r^2
3) square rooting both sides.
Sqrt(7/π)=r
Plug that into a calculator and you get about 1.4927
Now we multiply that by 4, giving us our new radius of about 5.9708
Plugging that number back into the equation A=πr^2 as r will give us 112.

Answer:
22.75 minutes or 22 minutes 45 seconds
Step-by-step explanation:
Okay, this is a working together question. Let’s walk through it together!
Firstly, let’s say the total volume of the swimming pool is x sq.meters
Now, the rate of the smaller hose would be x/65 while that of the larger will be x/35
Now, their combined rate would be x/65 + x/35 = 100x/2275
Now, since the volume is x, the time taken is simply, the volume divided by the joint rate. That is mathematically equal to x divided by 100x/2275
x * 2275/100x = 2275/100 = 22.75 minutes or 22 minutes 45 seconds
