1. Find the area of the shaded sector.
2. Find the length of the arc defined by the sector.
Answers
Answer:
1. 150π sq.ft 2. 10π ft
Step-by-step explanation:
Part 1Equation: Area of a sector = [tex]\frac{x}{360}[/tex] × π[tex]r^{2}[/tex]
Where:
x = internal angle
r = radius of circle
Values from problem:
x = 60
r = 30
Plug values into equation:
Area of sector = [tex]\frac{60}{360}[/tex] × π[tex]30^{2}[/tex]
Simplify:
60 divided by 30 equals [tex]\frac{1}{6}[/tex] and 30 squared equals 900 so...
[tex]\frac{1}{6}[/tex] × 900π
900π divided by 6 equals 150π so...
[tex]\frac{900}{6}[/tex] × π = 150π
150π sq. ft
Part 2Equation: Arc length = [tex]\frac{x}{360}[/tex] × 2πr
Where:
x = internal angle
r = radius of circle
Values from Problem:
x = 60
r = 30
Plug values into equation:
Arc length = [tex]\frac{60}{360}[/tex] × 2π30
Simplify:
60 divided by 360 equals [tex]\frac{1}{6}[/tex], and 2π × 30 equals 60π so...
[tex]\frac{1}{6}[/tex] × 60π
60π divided by 6 is 10π
[tex]\frac{60}{6}[/tex]π = 10π
10π ft

Suppose y varies directly with x, and y=98 when x=14. Write the direct
variation equation that relates x and y.
Answers
===========================================================
Explanation:
Since y varies directly with x, this means y = kx for some constant k.
Plug in y = 98 and x = 14 to solve for k
y = kx
98 = k*14
98/14 = k
7 = k
k = 7
Therefore, y = kx updates to y = 7x which is the equation we're after.
Answer:
y = 7x
Step-by-step explanation:
The general formula for direct variation is y = kx, where k is the constant of proportionality. If y = 98 when x = 14, then k must be 98/14. or 7, and so
y = 7x is the desired direct variation equation.

PLEASEE HELP
Answers
Explanation: First we would find the area of the pool. 6 times 12 is 72.
Since 4 feet is added add that to 6 AND 12.
Now multiply 10 and 16. 10 * 16 = 160.
Subtract 72 from 160. 160-72= 88 ft^2
