Answer:

Step-by-step explanation:
The figure is made up of a rectangle and two semicircles.
We find the area of the rectangle using the formula;



We find the area of one of the semicircles and multiply by 2;
The area of the semicircles

We substitute
and
to obtain;



The area of the figure is


To the nearest tenth we have;

The correct answer is A
Answer:
(simplified)
(in terms of pi)
Step-by-step explanation:
Since the salsa jar is basically a cylinder, to solve this we are using the formula for the volume of a cylinder:

where
Is the volume of the cylinder (salsa jar)
is the radius of the cylinder (salsa jar)
is the height of the cylinder (salsa jar)
We know from our problem that height of the full salsa jar is 10 centimeters; we also know that that there are only 4 centimeters of salsa left in the salsa jar. So, to find the the height of the missing salsa, we just need to subtract the height of the salsa from the height of the full salsa jar:
. Since the radius of the salsa jar never changes,
.
Now we can replace the values in our volume formula to find how much salsa is missing from the jar:





We can conclude that there are 471.24 cubic centimeters missing from the jar, or in terms of pi:
.
24 x 1/2 = 12,
use these numbers to make a problem
Answer: 7.3x + 5
Step-by-step explanation:
For us to solve the question, we have to solve 5.2x+8+2.1x-3 and the answer gotten will allow us know the equivalent expression.
= 5.2x+8+2.1x-3
= 5.2x + 2.1x + 8 - 3
= 7.3x + 5
Therefore, the correct answer is 7.3x + 5
Answer: m∠BCE = 63°
m∠BAD = 76°
Step-by-step explanation:
Problem 1:
Given
m∠BEC = 90°
m∠EBC = 27°
Total = 117°
Solution:
Subtract 180° - 117° = m∠BCE = 63°
Problem 2:
Given
m∠ADE = 52°
m∠ABE = 52°
Total = 104°
Solution:
Subtract 180° - 104° = m∠BAD = 76°
