Answer:
314 in
Step-by-step explanation:
The area of a circle is pi* r^2
If the radius is 10, then it is
pi* 10^2= 100pi
100*3.14 is around 314.16, using 3.14 for Pi it will be 314

Answer:
D
Step-by-step explanation:
The sum to infinity of a geometric sequence is
sum to infinity = 
here
= 144 and r =
, hence
sum = 
= 
=
= 192 → D
we can always find the x-intercept of any equation by simply setting y = 0, so let's do so
![\bf 4x+3y=36\implies 4x+3(\stackrel{y}{0})=36\implies 4x=36\implies x=\cfrac{36}{4}\implies x = 9 \\\\[-0.35em] ~\dotfill\\\\ ~\hfill (9~~,~~0)~\hfill](https://tex.z-dn.net/?f=%5Cbf%204x%2B3y%3D36%5Cimplies%204x%2B3%28%5Cstackrel%7By%7D%7B0%7D%29%3D36%5Cimplies%204x%3D36%5Cimplies%20x%3D%5Ccfrac%7B36%7D%7B4%7D%5Cimplies%20x%20%3D%209%20%5C%5C%5C%5C%5B-0.35em%5D%20~%5Cdotfill%5C%5C%5C%5C%20~%5Chfill%20%289~~%2C~~0%29~%5Chfill)
The first thing to notice with this question is that the volume of the tank is given in cm3 yet the rate at which the water leaks is in litres, so a conversion of units will be neccessary. We know that there are 1000cm3 for every litre so 45000cm3 is equivilent to 45 litres (45,000/1000 = 45). So what do we know now? Well the tank of water contains 45 litres, and every minute 0.75 litres is lost, so our objective is to find out how many miuntes go by before the tank is empty. In other words how many 0.75s go into 45, luckily division can help us out. 45/0.75 = 60 minutes.
Mark brainliest please
Hope this helps you
