Answer:
a. 7.54385 in^2
Step-by-step explanation:
surface area equation = 3.14 * r^2
diameter is 2 times radius
x=3.14 (1.55^2)
x=7.54385 in^2
Answer:
-31
Step-by-step explanation:
a - 8x will change to (-7) - 8(3) = -31
The experimental probability that the high temp will be below 45 F on the 29th day is, 4.5 out of 29 days, that is because 20 of the days have had lower temperatures, so they left 9 days of and from those 9 days, they could be lower or greater that 45F (50% each side), that is:
4.5/29 = 0.155 = 15.5%
that is the exp probability
Answer:
1.2%
Step-by-step explanation:
0.012 = 12/1000
to express it as %
12/1000 * 100
= 1.2%
Answer:
314
Step-by-step explanation:
Area is pie(r^2
10x10=100
100x3.14 is 314
