Answer:
- $855,000
- Dividend per share of common stock = $1.06
Step-by-step explanation:
1. Preferred Share dividends.
There are 300,000 preference shares and each of them got $2.85. Total dividends are;
= 300,000 * 2.85
= $855,000
2. Total dividends = $3,500,000
Dividends left for Common Shareholders (preference gets paid first)
= 3,500,000 - 855,000
= $2,645,000
Common shares number 2,500,000
Dividend per share of common stock = 
= $1.06
Answer:
A. 15π mi
Step-by-step explanation:
First find the circumference
C = 2*pi*r
C = 2 * pi*18
C = 36pi
The arc is 150 degrees
The fraction of the circle is
150/360 = 5/12
Multiply this by the circumference
5/12 * 36 pi
15 pi
