Answer:
C = 8π
Step-by-step explanation:
C = πd
d = 2r
Given : r = 4
d = 2r and r = 4
Plug in 4
d = 2(4)
2(4) = 8
D = 8
We then have C=πd and d = 8
So plug in 8
C = 8π
Answer:

Step-by-step explanation:
Given

Solving (a): The possible coordinates
We have:

This gives:



<em>(-2,8) is a point on the grid</em>

This gives:



<em>(7,5) is a point on the grid</em>

This gives:



<em>(-5,5) is a not point on the grid</em>
<em></em>

This gives:



<em>(1,3) is a not point on the grid</em>

This gives:



(1,7) is a point on the grid
So, we plot the following on the grid

Answer:
c
Step-by-step explanation:
c
Sam sold half as many as Odel.
That means Odel sold twice as many as Sam.
Let x = number of pizzas sold by Sam.
Then Odel sold 2x.
Altogether they sold 126
x + 2x = 126
3x = 126
x = 42
Since x is the number of pizzas sold by Sam, that is our answer.
Answer: Sam sold 42 pizzas.
