Answer:
A≈254 cm^2
Step-by-step explanation:
The area of a circle is given by formula: π
r^2
π has a constant value of 3.14 And the radius of the circle is 9
c

the area= π
r^2 = 3.14 x (9)^2 cm^2
=

Answer:
a) The basic rate of pay is 6 sterling pounds per hour.
b) The higher rate of pay is 10 sterling pounds per hour.
Step-by-step explanation:
Both segments of the curve are first order polynomials, which means that each have constant slopes.
a) The basic rate of pay is the value of the slope (
), in sterling pounds per hour, of the line for the first 20 hours worked, that is:
(1)
Where:
- Change in hours worked, in hours.
- Change in pay, in sterling pounds.
If we know that
and
, then the basic rate is:



The basic rate of pay is 6 sterling pounds per hour.
b) By using (1), we calculate the higher rate of pay below. If we know that
and
, then the higher rate is:



The higher rate of pay is 10 sterling pounds per hour.
We divide 325 by 48.
The answer comes out to 6.77
But since the number of buses must be a whole number, we will need 7 buses to carry the 325 students and teachers on a field trip.
