Find the volume of the candle using the formula for volume of a cylinder:
V = PI x r^2 x h = 3.14 x 3.4^2 x 6 = 217.79 cubic cm. Round to 217.8
Find the volume of the block: V = l x w x h = 15 x 12 x 18 = 3,240 cubic cm.
Now divide the volume of the block by the volume of a candle:
3240 / 217.8 = 14.88
Round to the nearest tenth = 14.9 candles.
Answer:
b = 12.6
Step-by-step explanation:
a*2 + b*2 = c*2
6*2 + b*2 = 14*2
36 + b*2 = 196
Subtract 36 from both sides
36 + b*2 = 196
-36 -36
b*2 = 160
Find the square root of both
b = 12.64911064 or 12.6
<span>First, we must convert the given fraction into a decimal number. So use a calculator or long division to convert the given fraction 11/4 to a decimal number. In this case, 2.75
Now just multiply the equivalent decimal 2.75 by 100 to convert it into a percent. So 100x2.75=275. Take note that we're simply moving the decimal point two spots to the right.
So the given fraction 11/4 is equivalent to 275%
so the answer is 275</span>
