56=2(pi)(r)
r=8.9127
pi(8.9127)^2=249.56cm^2
≈245cm^2 (3s.f.)
12. Divide 112 by 14 which comes to 8. Then take 96 and divide 96 by 8. Then you get 12
Answer:
$10.8 is left.
Step-by-step explanation:
Given that,
Total amount = $54
Left amount = 20%
We need to find how much tip should you leave. It means we need to find 20% of 54. So,

So, $10.8 is left.
Given:
The polynomial
is divided by (x+2).
To find:
The remainder.
Solution:
Remainder theorem: If a polynomial p(x) is divided by (x-c), then the remainder is p(c).
Consider the polynomial:

It is divided by (x+2). So, by the remainder theorem the remainder is p(-2).
Substituting x=-2 in the above polynomial, we get



Therefore, the remainder is -9.
