Answer:
C: 9076.3 cm^3
Step-by-step explanation:
Use the formula for the volume of a cylinder.
V=πr^2 times h
h=25
Here, I'm assuming 21.5 cm is the diameter, so divide 21.5 cm by 2 to get 10.75 as r.
V=(10.75^2)π times 25
115.5625π times 25
This is about 2889π
This simplifies best to choice C, which is about 9076.3 cm^3
However, if I was wrong about 21.5 cm being the diameter, my answer is wrong. If 21.5 cm is r, choice D is the correct answer. If 21.5 cm is the diameter, C is the answer.
1) 129.48 lbs : Multiply 156 by 0.17 to get 26.52, then 156 by 26.52 to get 129.48.
2) 1.96 : take 166.52 and divide that by 85. You will get 1.9590... and a lot of other crazy numbers. Round it to the nearest cent, you get 1.96.
3) 0.93 minutes : the faster time is 9.97 and the slowest is 10.9, subtract that and get 0.93.
4) 20.75 : add the prices up all together and you get 20.75
5) 18.32
6) 16.754
7) 56.44
8) I can't see the sign
9) 161.7
10) 737.49
11) 250
12) 405
13) 54.67
Answer: -1
Step-by-step explanation:
1. add the numbers
2. add 8 to both sides
3 add the numbers
4. divide both sides of the equation by the same term
5. divide the numbers then cancel the terms that are in both the numerator and denominator then move the variably to the left
Answer:
The father is 59
Step-by-step explanation:
lets say each of the kids are twelve
30*5=150-36=114=59+55
30*5+ 150 the age of everyone in the family added together
12*3= 36 the age of all the kids
150-36=114 the age of the adults added together
we know the mother is 4 years younger than the father so to state off you can take 114 and divide it by two to get what half of it is then take take numbers that are four apart to find the ages that add up to 114.
Answer:
1. So if you want to know how is math related to baking, I will show you how. Firstly, if you bake a cake, you'll all have to use some measurement, and if you calculate anything wrong or place the crazy amount, the cake you're trying to bake would turn out awful. That's where maths come to play. You would have to calculate ratios and much more, for example, one tee-spoon of sugar to 2 tee-spoons of water it's a 1:2 ratio of sugar to water. If you try to make double the amount of cake, then you'll all have to double the ratio, too, so the ratio will become 2:4, and that's how we would use math in baking a cake. If you for any reason put more than the required amount, the whole cake would be ruined like it might be too sugary, and you will have to retry and bake another one.
2. Yes indeed I've tasted a mess up the cake, and I think that the problem was that the cake batter was much sugary than I expected and that's why you guys have to calculate the perfect amount of ingredients, and that's how maths would help us in baking a cake
hope this helps you btw
