Answer:
a. $3.36
b. $70.86
Step-by-step explanation:
5% of $67.50 is $3.36

Hello!
You have to find the area of the first rectangle
13 * 25 = 325
Next find the area of the second rectangle
The base is quadripled
13 * 4 = 52
52 * 25 = 1300
Divide the area of rectangle 2 by the area of rectangle 1
1300/ 325 = 4
The answer is D. 4 times bigger
Hope this helps!
Perimeter = 2 × π × r
Perimeter = 2 × 3.14 × 9
Perimeter = 56.52
Perimeter = 56.52 ÷ 2
Perimeter = 28.26
The perimeter of a semicircle with a radius of 9mm is 28.26
Answer:
thats a acute angle witch is 62
Step-by-step explanation:
Answer:
200.96 = area of Shaded portions.
Step-by-step explanation:
Area of the 2 stars.
I don't know if you can see this or not, but the 4 quarter circles surrounding the star is found by subtracting a full small square surrounding the star
Area of 1 star = 4 * (1/4) pi * r^2
Area of 1 star = 3.14 * 4^2
Area of 1 star = 50.24
Area of both stars = 100.48
Area of the 4 semicircles at each end
The 2 semicircles at one end figure = 1 circle
The two circles gives the total area of the 4 semicircles.
Area 1 circle = pr * r^2
Area 1 circle = 3.14 * (8/2)^2
Area 1 circle = 50.24
There are 2 such circles = 100.48
Total area of both results
Total Area = 100.48 + 100.48
Total Area = 200.96
