Find the perimeter of the semicircle below. Use 3.14 for
pi.
1.6 ft

8.2ft

Step-by-step explanation:

Perimeter of a whole circle = 2*pi*r with radius r

Here we have 1.6ft as the radius so the whole circle's perimeter would be

2 * 3.14 * 1.6 = 10.048

We have half the circle so we half this number to 5.024.

Now we have to add the bottom straight line, which is two radii (two lots of 1.6)

5.024 + 1.6  + 1.6 = 8.224 which is rounded to 8.2ft

part a

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
