Answer:
26.17 cm²
Step-by-step explanation:
Applying,
A = πr²∅/360................. Equation 1
Where A = Area of the sector, r = radius of the circle the sector was formed from, ∅ = angle subtends by the sector at the center of the circle , π = pie.
From the question,
Given: r = 5 cm, ∅ = 120°, π = 3.14
Substitute these values into equation 1
A = 3.14(5²)(120)/360
A = 26.17 cm²
Hence the area of the sector is 26.17 cm²

Answer:
C
Step-by-step explanation:
Simply by substitution, you can figure out which function is shown on the graph.
-If the exponent x were zero, the number to the power x would be 1, because any number to the power of zero is 1. Therefore, the number in the front that is not being raised to the power of x, would be the y intercept, when the value of x is 0.
-Because B and D do not have 4 being multiplied to the number being raised to the x power, we can eliminate those.
-Then simply plug in the values of (1,8) into the functions.
A. f(x)=4*(8)^x
y=4*(8)^1
8=4*(8)^1
8=32
This is not true, so A is eliminated.
C. f(x)=4*(2)^x
y=4*(2)^1
8=4*(2)^1
8=8
This is true, so C is the answer.
