So it (-6-22)+(321) ? Before I solve this problem?
Answer:
Step-by-step explanation:
The formula of a volume of a cone:
<em>r</em><em> - radius</em>
<em>H</em><em> - height</em>
We have the diameter <em>2r = 10in → r = 5in</em>, and the height <em>H = 28in.</em>
Substitute:
1 quart = 4 cups
7 quarts = 28 cups
1 guest needs 2 cups
12 guests need 24 cups
She has 28 and needs 24, yes there is enough
The answer is three significant figures. The 1 and the 7 are both significant, because they are non-zero quantities.
This is where significant figures gets a little more complicated, because if a zero is used as a placeholder (i.e. 0.00027 cm) then it is insignificant.
But in the case above, the zero isn't being used as a placeholder, and thus, is significant.
I think the answer is negative 8 square root 726
then the answer if I am right sorry if I am not would be negative 88 square root 6
again sorry if wrong
