Answer:
The answer is : 70288.46
Step-by-step explanation:
Your father earned $34,000 per year in 1984.
The CPI in 2014 is 215 and the CPI in 1984 is 104.
The CPI or consumer price index examines the weighted average of prices of goods and services like transportation, food etc.
The Current income equivalent will be = value in 1984 X ( CPI in 2014/CPI in 1984)
= 70288.46
Is there a picture that goes with the question ?
The window has a shape of a semi-circle (half of a circle).
We know the diameter d = 12 ft.
The area of a (complete) circle is given by the formula:
A = π × r²
The radius can be found by halving the diameter:
r = d ÷ 2
= 12 ÷ 2
= 6 ft
Therefore the area of the circle will be:
<span>A = π × r²
= 3.14 × 6</span>²
= <span>3.14 × 36
= 113.04 ft²
And the area of the semi-circle:
A = </span><span>113.04 </span>÷ 2
= 56.52 ft²
Hence, the area of the window will be 56.52 ft².
