The cylinder shown here has a height of 7 centimeters and a radius of 4 centimeters.
Part A. What is the area of the base of the cylinder? Express your answer in terms of π. options are: 15 pi cm, 14 pi cm, 16 pi cm, 17 pi cm.
Part B: How many cubic centimeters of fluid can fill this cylinder? Express your answer in terms of π. options are: 112 pi cm, 110 pi cm, 113 pi cm, 107 pi cm.
Part C: Give a decimal approximation of your answer to the second question using 3.14 to approximate π. options are: 351.68 cm, 368.15 cm, 386.51 cm, 315.68 cm.
Answer:
A: 16[tex]\pi[/tex][tex]cm^{2}[/tex]
B: 112[tex]\pi[/tex][tex]cm^{3}[/tex]
C: 351.68[tex]cm^{2}[/tex]
Step-by-step explanation:
The cubic inches that can fill the cylinder is [tex]112\pi[/tex] and the decimal approximation 351.68 cm^3
The given parameters are:
Radius (r) = 4 cm
Height (h) = 7 cm
The area of the baseThe area of the base is:
[tex]A = \pi r^2[/tex]
So, we have:
[tex]A = \pi *4^2[/tex]
[tex]A = 16\pi[/tex]
Hence, the area of the base is [tex]16\pi[/tex]
The cubic inches that can fill the cylinderThis is the volume of the cylinder.
So, we have:
[tex]V = \pi r^2h[/tex]
Substitute known values
[tex]V = \pi * 4^2 * 7[/tex]
[tex]V = 112\pi[/tex]
Hence, the cubic inches that can fill the cylinder is [tex]112\pi[/tex]
The decimal approximationWe have:
[tex]V = 112\pi[/tex]
Expand
[tex]V = 112 * 3.14[/tex]
Evaluate the product
[tex]V = 351.68[/tex]
Hence, the cubic inches that can fill the cylinder is 351.68 cm^3

Answer:
0.917
Step-by-step explanation:
1ml=0.001L
Answer:
0.917 L
Step-by-step explanation:
Keep in mind that 1 L = 1000ml
since the number in ml does not go past 1000 it means that there is not even 1 liter. So your answer will be a decimal.
917 mL = 0.917 L

Answer:
Lowest: 78
Highest: 99
Step-by-step explanation:
Quiz 1 =A
Quiz 2 = B
B = 21 + A
2A = 57 + B
2A = 57 + (21 + A)
2A = 78 + A
A = 78
B = 21 + A
B = 21 + 78
B = 99

Find the perimeter of the following triangle. Round your answer to the nearest hundredth.
Step-by-step explanation:
step 1. The perimeter (P) is the length around the triangle.
step 2. P = 6 + 5 + L (the length of the hypotenuse)
step 3. L = sqrt(6^2 + 5^2) = sqrt(61) where sqrt is the square root
step 4. P = 11 + sqrt(61) = 18.81.

Evan cut a triangular piece of cloth to use in a quilt. The perimeter of the cloth is 934 centimeters. The base of the triangular cloth is 214 centimeters. The remaining two sides have the same length, s. Which equation models how to find the length of the other two sides of Evan's cloth?
Answer:
214 + 2s = 934
Step-by-step explanation:
First, we know that:
P = 934 cm
If the base (the bottom) of this isosceles triangle is 214 cm, that means the sum of the two remaining sides will be:
934 - 214 = 720
Because the two sides are equal, their measures can be represented by:
720/2
So a good equation would be:
934 = 214 + 2s
Where s = 360.
