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:
100
Step-by-step explanation:
The measure of an arc is twice the measure of the inscribed angle that intercepts it. The arc y° is intercepted by an inscribed angle marked 50°, so ...
y = 100
Answer:
The solution to the quadratic equation:
Step-by-step explanation:
Given the equation
6x - 0.2x · x = 0
Factor out common term -x
-x (0.2x - 6) = 0
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
solving
Multiply both sides by 10
Refine
Add 60 to both sides
Simplify
Divide both sides by 2
Simplify
Thus, the solution to the quadratic equation:
