Reasoning: the equation is -42•3.6= ? Even though it’s a negative, you multiply regularly so you can just use the absolute value for when you multiply but when you get your answer, don’t forget to see if you put a negative or if it’s positive- 42 x 3.6 so, when you multiply you get 1512. BUT there’s a decimal. And since there’s only one other number after the decimal, you put the decimal in the answer one space over [in between the 1 & 2] so the answer would be 151.2 but since there are two different signs, and when you have two different signs, you make it negative. So in the end it’s - 151.2 :)
you can find the radius for the area of the base 7 by dividing by like such 7/3.1459 the squared because remember its in r2 form which give you 1.5 then plug this in for one of two ways to solve A· 1/3 or V=πr2h
