1.) To find the piston displacement, you have to find the volume of cylinder. The formula for volume is V = pi*r^2*h, where V = volume, r = radius, h = height
2.) V = pi*r^2h
= 3.14*2.25^2*4.5 (bore = diameter; hence r = diameter/2) (height = stroke)
= 3.14*5.06*4.5
= 71.4978 or 71.50
3.) Since the engine has 8 cylinders, multiply the piston displacement by 8
= 71.50*8
= 572
Therefore, the total piston displacement of an 8-cylinder engine is D. 572
Answer:
A. high self-efficacy
Explanation:
Albert Bandura is a Canadian-American psychologist who was given birth to on the 4th of December, 1925 in Mundare, Alberta, Canada. He worked at Stanford University as a Professor Emeritus of social science in psychology and philosophy of action.
In 1997, Professor Bandura published his book titled "Self-Efficacy: The Exercise of Control" which typically deals with an individual's belief in his or her own competence.
According to Bandura, if someone is confident in performing a task, they most likely have high self-efficacy in regard to that particular task.
B) Social needs is the correct answer

Cooperatives provided a market for farmers' goods and products at lower costs. They did not work because farmers often had to buy on credit and the cooperatives were a cash-only system.
