Answer:
Step-by-step explanation:
The absolute value, as "distance from zero", is used to define the absolute difference between arbitrary real numbers, the standard metric on the real numbers. Complex numbers [ edit ] The absolute value of a complex number z {displaystyle z} is the distance r {displaystyle r} of z {displaystyle z} from the origin.
The area of the entire circle = pi r^2
The area of the shaded area = (40/360) * pi r^2
r = 9 cm
Area of the shaded area = 1/9 * 3.14 * 9^2
Area of the shaded area = 3.14 * 9
Area of the shaded area = 28.26
Notice one of the 9s disappeared. Where did it go?
You could begin the problem by writing out 9^2
Area = 1/9 * 3.14 * 9 * 9 Notice that 1/9 will cancel out 1 of the nines.
28.26 yds = Shaded area.
Answer:
B. 31
Step-by-step explanation:
The acreage Mr. Flowers intends to sell is 2/3 of his total, so is ...
(2/3)(23 1/4) = (2/3)(93/4) = 31/2 . . . . acres
Divided by 1/2 (which is the size of a lot), we will get the number of lots this will make:
(31/2)/(1/2) = 31/1 = 31
Mr. Flowers will have 31 lots for sale.
