Answer:
81pi mm^2
Step-by-step explanation:
The radius is 1/2 the diameter, and is used in finding the area of a circle.
The formula for this is
A = pi(r)^2
So the formula you would use is
A = pi (9)^2
= 81pi
Usually teachers accept it in terms of pi, but if not, you can use 3.14 and multiple it.
I hope this helped!
28/5ths which equally 595o
A) y - 8= -2/3 (x + 3)
B) y + 1 = 4 (x - 5)
C) y - 8 = -3/7 (x - 4)
D) y - 7 = 2/3 (x - 5)
E) y + 5 = -5/3 (x + 3)
Draw a triangle where the line connecting the two points is the hypotenuse. The difference in the X values between G and S is 5. The difference in the Y values is 4. Therefore One side of the triangle is five units long and one side is four units long. Using the Pythagorean theorem of A^2 + B^2 = C^2 we can plug-in 5 for A and 4 for B. Thus 25+16=C^2
C^2=41
C= square root of 41
the answer is 45 hope it helps
