Answer:
1. 60 cm^2
2. 132.67 cm^2
3. 72.67 cm^2
Step-by-step explanation:
1. Area of rectangle
A = LW = 5 cm * 12 cm = 60 cm^2
2. Area of circle
A = (pi)r^2 = 3.14(6.5 cm)^2 = 132.67 cm^2
3. Area of shaded region
A = area of circle - area of rectangle
A = 132.7 cm^2 - 60 cm^2 = 72.67 cm^2
Answer:
See below in bold.
Step-by-step explanation:
1. The area of the circle = 3.14 * radius^2.
The radius = 1/2 * 13 = 6.5 cm so the area is
3.14 * 6.5^2 = 132.67 cm^2 to the nearest hundredth.
2. Area of the rectangle = width * length = 5*12 = 60 cm^2.
3. Area of the shaded region = area of the circle - area of the rectangle
= 132.67 - 69 = 72.67 cm^2 to the nearest hundredth.

25^2-13^2=456 456 square root is 21.354... 21
7-4=3 10-7=3 13-10=3 we can see that this is an arithmetic sequence with a difference of 3 the nth term=the first term +(n-1) times the difference so a(n)=4+3(n-1)
