To find the area of the sector, Lita must multiply 74°/360° times the area of the circle, which is πr² (Option A).
<h3>What is the Area of the Sector of a Circle?</h3>
Area of sector = ∅/360 × πr², where ∅ = central angle, and r = radius of the circle.
Given the following:
The area of the circle she wants to find is: 74°/360°.
Since the area of the whole circle is, πr², therefore, to find the area of the sector, Lita must multiply 74°/360° times the area of the circle, which is πr² (Option A).

Answer:
C. x² + 7
Step-by-step explanation:
If f(x) = 2x² + 5 and g(x) = x² - 2, then
(f - g)(x) = f(x) - g(x)
= (2x² + 5) - (x² - 2)
= 2x² + 5 - x² + 2
= 2x² - x² + 5 + 2
= x² + 7
Answer:
3c - 12
Step-by-step explanation:
3(c-4), you have to distribute the number that is outside.
3*C - 3*4 = 3c - 12
