Answer:
if 28 cm is the radius then:
area = 2461.76 cm²
if 28 cm is the diameter then:
area = 615.44 cm²
Step-by-step explanation:
area = πr² = (3.14)(28²) = 2461.76 cm²
The Formula for the compound interest is:

A = Amount Accumulated = $5000
P = Principal Amount = $1250
n = compound period in a year = 4
r = Interest Rate
t = Time in years = 12
Using the values in the formula, we get:

Thus, in order to achieve the given conditions, 11.72% interest rate is required.

Answer:
78
Step-by-step explanation:
for the right side we can just do 14*2 since there are two people per seat and 14 rows
14 *2 is 28
for the left side we just do 14*3 since there are three people per seat and 14 rows
14*3 is 42
Then we have to add the 8 students that can fit in the very back seat
42 + 28 + 8
28 + 8 is 36
42 + 36 = 78
