Answer:
Step-by-step explanation:
Always use your imaginary scissor:
Cut the above and below circle and the cylinder role it down-ways like a carpet and you will end up with two circles and a big rectangular.
Surface circle: 7 * 7 * 3,14 = 153.86
Surface carpet: 20 * circle exterior (or the length of the circle)= 20 * 2* 3.14 * 7
Results:
153, 86 * 2 (because we cut 2 circles from the cylinder) + 132,6 = 439.6
Answer: A
Answer:
- Jon - Andrea = 1/10
- Callie - Jon = 3/10
Step-by-step explanation:
In terms of tenths, the distances each hiked are ...
- Andrea — 4/10
- Jon — 5/10
- Callie — 8/10
Then the differences of interest are ...
Jon - Andrea = 5/10 -4/10 = 1/10
Callie - Jon = 8/10 - 5/10 = 3/10
__
Jon hiked 1/10 of the trail more than Andrea.
Callie hiked 3/10 of the trail more than Jon.
(25000-f)(.03)+.05f=1100
750-.03f+.05f=1100
750+.02f=1100
.02f=350
f=$17500
So Mary invested $17500 @ 5% and 7500 at 3% to earn $1100 in interest.
