Answer:
125.60
Step-by-step explanation:
the formula for the area of a cylinder is A=2πRH+2πRsquared. I find it easiest to multiply pi by 2 instead of anything else which is 6.28. Then I multiply the radius (2) times the height (8) equaling 16. Then you multiply that number by 6.28. Equaling 100.48. Then you have to do the second part which is radius (2) squared equaling 4. Then you multiply that by 6.28, equaling 25.12. then you add the two sums (25.12+100.48=125.60).
hope that makes sense!!
Answer:
18x^5 +28x^2
Step-by-step explanation:
20x^2 + 14x^5 + 8x^2 + 4x^5
Combine like terms
20x^2 + 8x^2 + 4x^5+ 14x^5
28x^2 + 18x^5
We usually write the highest power term first
18x^5 +28x^2

Answer:
2.6768·10^(-14) (Answer C)
Step-by-step explanation:
Problem 4: We ADD the powers of 10: 10^6·10^(-3) = 10^3. Also, 3.6·1.7 = 6.12. Therefore, Answer D is correct.
Problem 5: Again we ADD (combine) the powers of 10: 10^(-10)·10^(-5) =
10^(-15). 4.78·5.6 = 26.768. Our intermediary answer is thus:
26.768·10^(-15). This must be rewritten in the form x.xxxx, so here we have:
2.6768·10^(-14) (Answer C)
Answer:
Step-by-step explanation:
There are many ways this could be done, but the simplest way is to divide 18 into 72. That gives 4. So each plot is 4 * 20 = 80 m^2
If you are willing to use fractions, the answer could be 20*72 / 18 = 8 * 10 which is more feasible and still gives 80, but the land may not permit it. However math will.
It's hard to give an exact answer when it is this open ended.
