Answer 2

So to find the volume of a sphere we use this equation....

\(\Huge{V=\frac{4}{3} \pi r^{3}}\) Where \(\large{r}\) is \(\large{70}\)...so input..

\(\Huge\color{purple}{V=\frac{4}{3} (3.14) 70^{3}}\) Simplify....

Answer 3

Once we find the volume of a whole sphere we would then divide it by four to get the volume of a quarter-sphere tank....

Answer 4

Hmmmm I think I get it

Answer 5

So you were able to come up with your answer?

Answer 6

plugging it all in now, sorry if its taking me a while my computer is so slow today

Answer 7

its alright ^^

Answer 8

I got 0.0000122060252672497 as my answer lol

Answer 9

\(\Huge{V=\frac{4}{3}(1,077,020)}\) We multiply it by 4....

\(\Huge\color{orange}{V=\frac{4,308,080}{3}}\) In which you would divide by 3....

Answer 10

1436026.6666666666666666666666667

Answer 11

Is this right?

Answer 12

Yup ^^ Now we need to find a quarter of a sphere so we would divide this number by 4....

\(\Huge{\frac{1436026.667}{4}}\)

Answer 13

Why would we divide by 4?

Answer 14

oh and I got 359006.66666666666666666666666667

Answer 15

Correct but they want you to round to the nearest who so it would round to

\(\Huge{359,007}\) Since 60 is closer to 100....

Answer 16

Ohhhh ok, thanks! I'll explain how I came to that on my assingment, I'll post my next/last question in a bit.
