Answer:
78.10 cm^2
Step-by-step explanation:
The area of the shaded region is the area of the rectangle subtracted from the area of the circle.
area of circle = (pi)r^2
area of rectangle = LW
shaded area = area of circle - area of rectangle
shaded area = (pi)r^2 - LW
shaded area = (pi)r^2 - LW
shaded area = (3.14159)(6 cm)^2 - (7 cm)(5 cm)
shaded area = (3.14159)(36 cm^) - 35 cm^2
shaded area = 113.097 cm^2 35 cm^2
shaded area = 78.097 cm^2
Answer: 78.10 cm^2
280 is the answer

He should not have simplified 3/7 to 1/7 as they do not equal - he now has 2 less sevenths than before.
This was a quadratic formula
sin is the y value
here is me solving it
By the PEMDAS rule, as long as the stuff inside the parentheses add up to 42, it would be correct. Therefore:
A. Correct because 40 + 2 = 42
B. Correct because 20 + 22 = 42
C. Incorrect because 4 + 20 = 24 ≠ 42
D. Incorrect, because 4 + 2 = 6 ≠ 42
