Cylinder A -
Surface Area:
<em>A = 2πrh + 2πr^2</em>
<em>A = 2 · π · 5 · 7.5 + 2 · π · 25 ≈ 392.69908</em>
<em>A = </em>392.7 cm^2
Volume:
<em>V = πr^2h</em>
<em>V = π · 25 · 7.5 ≈ 589.04862</em>
<em>V = </em>589 cm^3
Cylinder B -
Surface Area:
<em>A = 2πrh + 2πr^2</em>
<em>A = 2 · π · 3.5 · 5 + 2 · π · 12.25 ≈ 186.92476</em>
<em>A = </em>186.9 cm^2
Volume:
<em>V = πr^2h</em>
<em>V = π · 12.25 · 5 ≈ 192.42255</em>
<em>V = </em>192.4 cm^3
We have to take the population of Germany divided by the population of Martinique:
(8.27*10^7)/ (4.05*10^5)= 204.198.
Conclusion: The population of Germany is about 204 times as large as the population of Martinique.
Hope this helps~
Answer:
Ed would earn $4480
Step-by-step explanation:
you could solve this by ratios
make x = the amount of money he would earn if he worked 40 hrs
step 1: write the ratio
112/8 = x /40
step 2: cross multiply
8x = 4480
step 3: isolate x by dividing
8x/8 = 4480/8
answer: x = 560
Answer: g = 40f
Step-by-step explanation:
Since one water filter will clean 40 gallons of water, the equation that can be used to find g, the total number of gallons that will be cleaned by any number of filters f will be gotten by multiplying f by 40. This will be:
g = f × 40
g = 40f
For example, the gallons of water that 4 water filters will clean will be:
= 40f
= 40 × 4
= 160 gallons
