Answer: C . 147π / 4 mi²
Concept:
The sector is the part of a circle is enclosed by two radii of a circle and their intercepted arc.
A = (θ / 360) πr²
θ = angle of the sector
π = constant
r = radius
Solve:
<u>Given variable</u>
θ = 270°
r = 7 mi
<u>Given formula</u>
A = (θ / 360) πr²
<u>Substitute values into the formula</u>
A = (270 / 360) π (7)²
<u>Simplify exponents</u>
A = (270 / 360) π 49
<u>Simplify by multiplication</u>
A = (147 / 4) π
A = 147π / 4
Hope this helps!! :)

<u>Corrected Question</u>
Suppose the value R(d) of d dollars in euros is given by
. The cost in dollars to purchase and ship n purses is given by P(n)=66n+23. Write a formula for the cost, Q(n) in euros to purchase and ship n purses.
Answer:

Step-by-step explanation:
The value R(d) of d dollars in euros is given by 
Therefore:


The cost P(n) in dollars to purchase and ship n purses is given by:

Therefore, the cost, Q(n) in euros to purchase and ship n purses

Answer:
option C
y = 2
Step-by-step explanation:
Given in the question,
a co-ordinate = (-2,2)
x = -2
y = 2
Equation of the straight line
y = mx + c
<em>here m = gradient of the line</em>
<em> c = y - intercept</em>
<em />
<h3>we know that gradient of the horizontal line = 0</h3>
plug value in the equation above
y = (0)x + 2
y = 2
