Answer:
D 12.57
Step-by-step explanation:
diameter = 4inches hence radius = 2inches
if the crust covers the full pizza "around", technically its the circumfrence
hence 2πr
2×π×2= 12.566 ~ 12.57
Answer:

Step-by-step explanation:
Assuming we want to find the equation (74,2) and (4,9)
This is an equation of a straight.
Let this equation be y=mx+b.

We substitute the slope and (4,9) to get:

We rewrite in standard form to get:

Answer:
440
Step-by-step explanation:
55x8. 8x5=40 carry the 4. 8x5=40+4=44 so it is 440
Tan x =opposite/ adjacent =9/5
x= arctan(9/5)≈61
