Step-by-step explanation:
To place the correct symbol between the two numbers -27 -39
A review of the number line system shows a split of numbers between negative and positive numbers as illustrated in the attached.
The numbers to the right are greater than the numbers to the left. For instance, on the number line shown, 5 is to the right of 1 while 1 is to the left of 5 (as shown in diagram 1 in the attached). As such, 5 > 1.
A review of diagram 2 in the attached shows that -27 is to the right of -39. As such, the sign to be place in between them is the greater than sign >.
Answer:
<em>(6pi + 10) m^2</em>
Step-by-step explanation:
The bottom right part is a rectangle, 2 m by 5 m.
A = 2 m * 5 m = 10 m^2
The curved part is a larger semicircle with an inner semicircle missing.
We find the area of the larger semicircle and subtract from it the area of the smaller semicircle.
Larger semicircle: radius = 4 m
area of semicircle = (1/2)(pi * r^2) = (1/2)(pi)(4 m)^2 = 8pi m^2
Smaller semicircle: radius = 2 m
area of semicircle = (1/2)(pi * r^2) = (1/2)(pi)(2 m)^2 = 2pi m^2
Area of circular part: 8pi m^2 - 2pi m^2 = 6pi m^2
Total area: 6pi m^2 + 10 m^2 = (6pi + 10) m^2
