<u>Answer:</u>
The area of one side of a disc is 314 square inches
<u>Explanation:</u>
Given the radius of the disc is 10 inches
The disc is in circular shape and the area of a circle is determined by
A = 
, where
A is the area and r is the radius and π = 3.14
Substituting values in the formula,
A = 
A = 
= 341 sq. inches
Therefore, the area of one side of a disc is 314 square inches
Answer: 
Step-by-step explanation:
Given
The area is bounded by 
and x-axis from [0,2]
The volume generated for 
when rotated about the x-axis in the interval [a,b] is
Insert the values

Answer:
y = 4 sin (2x) -1
Step-by-step explanation:
y = 4 sin (2x) -1
-------------------
13/16 divided by 7/8 is 13/14
13/14(7/8)= 91/112= 13/16
To get the average add up the totals and divide by the amount
(12.5+13+13)/3
=38.5/3
=12.833
