Sector area = (central angle / 360) * PI * radius^2
sector area = (72 / 360) * PI * radius^2
radius^2 = sector area / [(72 / 360) * PI]
radius^2 = 16.2 * PI / [(1 / 5) * PI]
radius^2 = 16.2 / .2
radius^2 = 81
radius = 9

Answer:
C. 4.3
Step-by-step explanation:
Given that
n = 17
P = 1/4
Using binomial
Mean = np
Mean = 17 × (1/4)
= 17 × .25
= 4.25
Approximately = 4.3

- Given - <u>an </u><u>equation</u><u> </u><u>in </u><u>a </u><u>standard</u><u> </u><u>form</u>
- To do - <u>simplify</u><u> </u><u>the </u><u>equation</u><u> </u><u>so </u><u>as </u><u>to </u><u>obtain </u><u>an </u><u>easier </u><u>one</u>
<u>Since </u><u>the </u><u>equation</u><u> </u><u>provided </u><u>isn't</u><u> </u><u>i</u><u>n</u><u> </u><u>it's</u><u> </u><u>general</u><u> </u><u>form </u><u>,</u><u> </u><u>let's</u><u> </u><u>first </u><u>convert </u><u>it </u><u>~</u>

Explanation:
We already have phone A 5.3 cm
We just need to find phone B
First we need to find what one-third is as a decimal
Which is 0.3
Now add 0.3 to 5
0.3 + 5 = 5.3
Answer: neither phone a and Phone be 05.3 cm
