For Part A) multiply the radius (28) by two in order to get the diameter. Take that product and multiply it by the "abbreviation" of pi that they give you (3.14). BAM, you get the circumference of the circle.
Part B) Because you're covering something, you need to find the area rather than the circumference (the distance around a circle). It's like needing to know the number of square units that can fit on a wall to figure out how many gallons of paint you need to cover it entirely.
Part C) Circumference, just I said.. the key word here is around. Distance around a circle !!
Answer:
66.66
Step-by-step explanation:
So for this one all you really have to do is turn 2/3 into a precent which is pretty easy.
This fist step to this would just be dividing 2 and 3
2/3=0.66666666666666666666 (and on and on and on)
Now just move the decimal 2 times to the right
66.6666666666666666666666
And of course round it, and in this case to the hundreth place
66.66
The formula is s = r * angle
Angle must be in RADIANS for the formula. Since the picture gives 135 degrees you either convert in the formula by adding the conversion factor, (s = r * angle * pi/180) or knowing that 135 degrees is 3pi/4.
s = 6 * 3* 3.14/4
s = 14.1
