Answer:
210 ways
Step-by-step explanation:
7 P 3 = 210 ways
or 7 C 3 = 35 choices of 3 posters which can bearrranged in 6 different ways 6 * 35 = 210 ways
b. 12π
C= 2πr
R= D/2= 12/2= 6
C= 2x3.14x6
2x6= 12
C= 12π
122500
The formula
A=p(1+rt)
A ?
P 100000
R 0.075
T 3 years
A=100,000×(1+0.075×3)
A=122500
