To calculate for area given the circumference we proceed as follows:
C=2πr
where:
r=radius
thus given that C=25 1/7 in=176/7
thus plugging in our formula to solve for r we get:
176/7=2πr
thus
r=4.002~4.00 in
hence the area will be:
A=πr²
A=π×(4²)
A=50 2/7 in²
18·8.7= 156.6
23·56.1= 1290.3
47·5.92=278.24
Answer:
Step-by-step explanation:
Given that:
R(x) = 
+ 34x − 17
As we know that derivative of revenue function is marginal revenue function .
We will use following rules of derivative
=> dR/ dx = 
=> R' (x) = 
=> R '(2000) = 
= 34
The revenue when 2000 units are sold is:
R(2000) = 
+ 34*2000 − 17 = $69,783

8•8=64
Answer:
65°
Step-by-step explanation:
all angles in a trapezium equate to 360°
R is 115°
115+115=230
360-230=130
130÷2=65
