Answer:
A. 4.26 in^2
Step-by-step explanation:
Step 1: Find the area of the sector DBC. Here we have to use the formula.
Area of a sector = Central Angle/360 *π
The area of the sector DBC = (54/360)*3.14*
= 30.16
Step 2: Area of segment CFD = Area of the sector DBC - Area of the ΔCBD
= 30.17 - 25.9
Area of segment CFD = 4.27in^2
The usual rules of addition and multiplication apply to complex numbers as well as to real numbers. The true statements are ...
- x + y = y + x . . . . . . . . . . . . . . . commutative property of addition
- (x × y) × z = x × (y × z) . . . . . . . . associative property of multiplication
- (x + y) + z = x + (y + z) . . . . . . . . associative property of addition
