answer is:
Circum: 25.13274 cm^2
Area: 50.26548 cm^2
Step-by-step explanation for the CIRCUMFERNCE ONLY:
Original equation for the circumference of a circle:
C=2(pi)r
We will use 3.14 as pi
We know that the diameter of a circle is 2 times the radius, so in order to find the radius all we have to do is divide the diameter by 2.
8/2 = 4
So now we know what the radius is equal to.
4
So now just plug in your numbers to the original equation
2 X (3.14) X 4
25.13274
If we were to round up the answer would be
25.13
Hope this helps!

Joseph plots the speed of his car and time on a scatter plot. The equation for the line of best fit on his scatter plot is y = -15x + 60, where x is the time in hours and y is the speed in miles/hour. Which statement describes the situation correctly?
A.
The initial speed is 60 miles/hour, and his speed decreases by 15 miles/hour every hour.
B.
The initial speed is 60 miles/hour, and his speed increases by 15 miles/hour every hour.
C.
The initial speed is 0 miles/hour, and his speed increases by 15 miles/hour every hour.
D.
The initial speed is 5 miles/hour, and his speed increases by 30 miles/hour every hour.
Answers
Answer:
A
Step-by-step explanation:
His speed change is the slope or -15, decreases by 15 miles/hour
when he starts, his speed is 0*-15+60 = 60 miles/hour

Ulet rolls 2 fair dice and adds the results from each. Work out the probability of getting a total of 7.
Answers
Answer:
7/ 36
Step-by-step explanation:
Roll of 2 fair six sided die :
Sample space = 6² = 36
Sum of 7:
(1,6) ; (6,1) ; (3,4) ; (4,3) ; (2,5) ; (5,2) = 6
Probability = required outcome / Total possible outcomes
Required outcome = 7
Total possible outcomes = 36
P(obtaining a sum of 7) = 7 / 36

what is the distance between (0.-3) and (9.6)
Answers
Answer:
d = 12.7 when rounded to the nearest tenths
Step-by-step explanation:
Distance formula:
d=√((x_2-x_1)²+(y_2-y_1)²)
Your ordered pairs (0, -3) and (9, 6)
d=√((9-0)²+(6-(-3))²)
d=√((9))²+(6+3))²)
d=√(81 + (9)²)
d = √162
d = 12.727...
d = 12.7 when rounded to the nearest tenths

Option 2: √
Table one:
y=8-2
y would be 6 then this would be correct..
Table two:

if y=20 then x would be 5 and if y is 16 then x=4.

Answer:
2 nickels, 9 dimes
Step-by-step explanation:
When there are a number of overlapping shaded areas on the graph, I find it convenient to use the reverse of the inequalities. That makes the unshaded area the solution space. Here, the vertices of the triangular solution space are ...
(2, 9), (2, 13), (6, 9)
Any of the grid points within (or on) this triangle is a possible solution. One of them is (2, 9) corresponding to 2 nickels and 9 dimes.
