Answer:
D
Step-by-step explanation:
This is the veritcal angles theorem
For the first one write 9 divided by 2 gives your your radius an it’s 3.5. the formula is 2 x 3.14 x radius and that gives you 21.98.
the 2nd one is 2 x 3.14 x 9 = 56.52
the 3rd is 2 x 3.14 x 5= 31.4
formula is always 2 x 3.14 (or pie) x radius
to get your radius from your diameter you do your diameter divided by 2
0.24 as a fraction equals 6/25
Answer:
Multiplied by -4
Step-by-step explanation:
Since it is being switched off from negative to positive, this means that it has to be a negative number. Since two negatives make a positive, then -5*-4=20, and since a negative and a positive make a negative, it would be 20*-4=-80
