Answer:
54.22 mm
Step-by-step explanation:
Find the circumference of the circle and then divide it by 2.
We start with the formula for the circumference for the circle:
C = 2πr
To find r, divide 22 by 2:
22/2=11
Now find the cicumference:
C = 2πr = 2(3.14)(11) = 108.46 mm
NOW, to find the perimeter of the semicircle, divide the circumference by 2:
108.46/2 = 54.22 mm
Answer:
y = .003x + 25
Step-by-step explanation:
y = .003x + 25
Answer:
60m^2
Step-by-step explanation:
Ok so if you subtract the 18 by 12 then divide by two you get the missing lengths of each of te triangles. If you then use the area of a trapezoid formula (think about it like pulling one triangle off one side and putting it next to the other to make a rectangle) you just do L x W and get 60.
Answer:
21
Step-by-step explanation:
He will guess correctly 25% of the time.
He has 84 questions
25% of 84
.25 * 84
21
We should expect that he will get 21 questions correct
