(Second choice)
Perimeter= 50.24 inches, Area=164.48 square inches
Step-by-step explanation:
Compound Shapes
The figure in the image can be split into four half circles and a square.
The area of a circle of radius r is:
The area of a square of side length x is:
Each semicircle has a radius of r=4 inches, thus the area of the four semicircles is twice the area of a circle:
The square has a side length of x=8 inches:
The total area of the shape is
The perimeter of the figure corresponds to the length of 4 semicircles or twice the length of a circle:

(Second choice)
Perimeter= 50.24 inches, Area=164.48 square inches
Perimeter = 65.12 in
Area = 292.48 in^2
which agrees with the second answer choice
Step-by-step explanation:
The perimeter is going to be the addition of the sides of the rectangle external to the composite figure ( 12 + 16 + 12 = 40) PLUS the length of half of the circumference or radius 8 inches (which is pi * radius = 3.14 * 8 = 25.12 in)
Then the total perimeter is:
Perimeter = 40 in + 25.12 in = 65.12 in
The are is going to be the area of the rectangle (12 * 16 = 192 square inches) PLUS the area of the semicircle of radius 8 in (pi *radius^2 /2 = 100.48 square inches).
Therefore the total area is:
Area = 192 + 100.48 = 292.48 in^2
The perimeter and area of the composite shape is:
B. Perimeter = 19.42 inches; Area = 26.13 square inchesRecall:
Area of a circle = πr²
Perimeter of circle = 2πr
Area of triangle = 1/2(bh)
The composite shape given is composed of a triangle and a semicircle.
Perimeter of the composite shape = Perimeter of semicircle + the length of the two sides of the triangle
Perimeter = 1/2(2 × 3.14 × 3) + 2(5) = 19.42 inches
Area of the composite shape = area of semicircle + area of triangle
Area = 1/2(3.14 × 3²) + 1/2(6 × 4)
Are = 14.13 + 12
Area of the composite shape = 26.13 square inches.
Therefore, the perimeter and area of the composite shape is:

C) Perimeter = 46.28
Step-by-step explanation:
The lengths of the sides on the bottom half of the shape are given as :
left = 10, bottom = 20, right = 10 = 40.
Need to find the perimeter of the semicircle at the top of the shape.
Perimeter of a circle is the Circumference = 2πr
So the perimeter of a semicircle = πr
= 3.14(2)
= 6.28
Add up the lengths of the left, bottom, right, and top: 40 + 6.28 = 46.28
Since there is only one option for Perimeter = 46.28, there is no need to solve for the Area.
For 1 flavor there are 9 topping
Therefore, for 5 different flavors there will be 5*9 choices
No of choices= 5*9
