Answer 1

Answer:

1. 4.7

2. 5,082

Step-by-step explanation:

1. To find the volume of a cone you use this formula $V=\pi r^{2} \frac{h}{3}$. The diameter is 3 so to find the radius, divide it by 2 (3/2=1.5) and we know the height. Input the numbers into the formula and solve $V=\pi (1.5)^{2} \frac{4}{3}$ which is equal to $3\pi$. To find HALF, divide that answer by 2. $3\pi /2= 4.71239$, round to the nearest tenth, making the answer 4.7!

2. To find the volume of a rectangular prism you use $V=lwh$. Input the numbers, $V=(30)(12)(16)$ to find the amount of water for the bigger tank (5,760). Now follow the same process to find the amount of water for the smaller tank $V=(12)(6)(9)$ which is 678. Now subtract the smaller tank amount (678) from the larger tank since you're taking the water from the bigger tank to fill the smaller one which equals 5,082.
