Remember that the cone volume formula is , with r = radius and h = height. Using our information, we can form our equation as such: (I'll be keeping the answer in pi form.)
Firstly, solve the exponents:
Next, multiply 4 and 19/3 together and your answer should be (rounded to the hundreths): V = 25.33π un^3
First let's find an equation to solve this with... if Tommy has 5 more toy cars than Billy, Tommy has c + 5 and so if you have 12 = c + 5, the answer is 7
