Answer:
The circumference is 31.43 cm
The ratio of the circumference to the diameter is equal to 3:1
Step-by-step explanation:
Thed formular for the circumference of a circle is 2r or
d
where d = diameter and r = radius
if d = 10 cm, and = 3.143, then circumference of the circle can be given as
3.143*10 = 31.43 cm
The ratio of the circumference to the diameter can be given as 31.43:10
and that can be given as 3.143:1
or 3:1, for the nearest whole number
Answer:
The GDP gap is 9 % when there is 4.5 % unemployment.
Step-by-step explanation:
The statement shows a reverse relationship, where an increase in unemployment is following by decrease in potential GDP and can be translated into the following rate:
The GDP gap at a given increase in unemployment can be estimated by the following expression:
Where:
- GDP gap-unemployment increase rate, dimensionless.
- Increase in unemployment rate, measured in percentage.
- GDP gap, measured in percentage.
If and
, the GDP gap is:
The GDP gap is 9 % when there is 4.5 % unemployment.
