Answer:
122.24 is the approximate answer
Step-by-step explanation:
The Logo is made up of 2 semicircles and 1 rectangle
Two semicircles make one circle
The formula for a circle is π
The radius (r) is 4 because the diameter is 8
so you plug it in and get 16π
The approximate value of π is 3.14
16 times 3.14 is 50.24
so to calculate the area of the whole logo just add
The 4 subintervals are given: [2, 4], [4, 7], [7, 9], and [9, 10].
Each subinterval has length: 4 - 2 = 2, 7 - 4 = 3, 9 - 7 = 2, and 10 - 9 = 1.
Over each subinterval, we take the value of the function at the right endpoint: 3, 8, 15, and 18.
Then the integral is approximately
so 78.0 is the correct answer.
