Answer:
In terms of π, the area of the shaded sector is 108πin²
Step-by-step explanation:
Area of the shaded sector, which is the major sector=x°/360(πr²)
A=270/360×π×(12in)²
A=¾π×144in²
A=108πin²( in terms of π)
Answer:
y = 13.8
Step-by-step explanation:
Plug in 7.2 for x in the first equation.
y = 1.5x + 3
y = (1.5)(7.2) + 3
Simplify. First, multiply, then add (following PEMDAS).
y = (1.5)(7.2) + 3
y = (10.8) + 3
y = 13.8
13.8 is your answer for y.
