Answer:
6.25π cm²
Step-by-step explanation:
pi = π
Circumference = 5πcm
Now first we should find radius(r)
2πr = 5π cm
pie will be cancelled and we get here
r = 5/ 2 cm
Therefore r = 2.5 cm
Now
Area (A) = πr²
= π * 2.5²
= 6.25π cm²
For example, a mix number like 1 ½ basically equals to a whole and a half and in this case the whole would be 2 and the half of 2 is 1. hence, the improper fraction of 1 ½ is 3/2.
Answer:
21.6 $ / h
Step-by-step explanation:
Since it is a raise you'll calculate by multiplying the $ / h by (1 + % / 100)
In this case 1 + % / 100 = 1 + 20 / 100 = 1 + 0.20 = 1.20
1.20 * 18 = 21.6 $ / h
NB.:
If it was a decrease by 20 % => 1 - 20 / 100 = 1 - 0.20 = 0.80
You would multiply the $ by 0.80.
