The circumference of the circle formula is 2πr or πd.
We will use πd since we know the diameter.
C = πd
C = (3.14)(16)
C = 50.24
Hope this helps :)
Answer:
9.44 x 10^4 in scientific notation
Step-by-step explanation:
The depth of the joist that was drilled by Freddy is 5 1/3 inches.
From the information given, we are informed that Freddy drilled into a piece of wood and a joist to attach them and that be drilled 4 inches and the wood was 1 1/3 inches thick.
Therefore, to get the depth that was drilled, we'll need to add the fractions given together. This will be:
= 4 + 1 1/3
= 5 1/3 inches.
Therefore, the depth of the joist that was drilled by Freddy is 5 1/3 inches.

The height is 5.
Since V=Base*height, I just divided the volume by the base.
175/35
=5
So the height would be 5. You can check to see if it's true by multiplying 35*5, which gives you 175.
A) 0.59 uses 2 sig figs
B) 100.6 uses 4 sig figs (the zeros in this case are significant)
C) 98.42 uses 4 sig figs
D) 1.045 uses 4 sig figs (the zero is between other sig figs so it's significant)
Every choice but choice A has 4 sig figs. So the answers are B, C, and D
