Answer:
66.6% (see below)
Step-by-step explanation:
Each sphere 4/3
r²=4/3(4²)=268.08cm³
Assuming the tube is the same width and height as the three spheres,
V=r²h=(4²)24=1206.37
The three spheres are 268.08*3=804.24cm³
The tube is 1206.37cm³
<u>I’m not sure if your question is asking the percentage of the tube that’s filled, or the percentage that’s unfilled.</u>
Filled: 804.24÷1206.37=0.66666=66.6%
Unfilled: 1206.37-804.24=402.13
402.13÷106.37=0.33333=33.3%
Answer:
C. 130
Step-by-step explanation:
Since the sum of the interior angles for a quadrilateral shape is 360 degrees, you take 55 and 45 away from 360 to get 260. You need to then divide that number by 2 to get Q and S, but you are looking for Q in this case, so the answer is 130.
I think you want to say the expression 3m2+2p2-15. The only thing you need to do is to replace the letter with the number. So the expression is 3*3^2+2*10^2-15=212.
