Answer:
Let's imagine the image of the zoo.
The diameter is basically the length of the circle.
The penguin swam the radius.
To find the radius, we need to divide the diameter by 2.
The diameter is 20 meters.
20 
2 = 10 meters.
2 x pi x 10 = 62.83185307
62.83185307/2 = 31.41592654
Answer = 31.41592654
Answer:
$29.60
Step-by-step explanation:
$11.20/14 miles = $0.80 per mile
$0.80 x 37 = $29.60
<span>75°
Since â–łABC is similar to â–łXYZ, that means that angle A equals angle X, angle B equals angle Y, and angle C equals angle Z. So let's look at the data we have.
Angle A measures 45° and angle C measures 60°. That means that angle B measures 180° - 45° - 60° = 75° since all triangles have 180° and we've been told the measurement of two of the angles. And since angle Y is equal to angle B (which we just calculated), that means that angle Y is also equal to 75°</span>
Your teacher is right. There is no reason to use algebra, which is misused in many problems as a shortcut, and slows the actual learning of math skills.
Here, the solution is as follows:
1. Find the volume of water in tank X.
2. Find the TOTAL base area of the three tanks, imagine that you have a larger tank with the same base area as the sum of the three.
3. Find the height of water in the new tank.
1. Find the volume of water in tank X.
Volume = 32*20*39.5=25280 cm^3
2. Find the TOTAL base area of the three tanks, imagine that you have a larger tank with the same base area as the sum of the three.
Total base area = 32*20 + 30*16 + 20*8 = 640+480+160 = 1280 cm^2
3. Find the height of water in the new tank
Height = Volume / base area
= 25280 / 1280
= 19.75 cm
