Area of Circle= πr2

Radius= 12/2= 6

Area of Circle= 3.14*6*6 =113.04

Area of shaded region= 144- 113.04 = 30.96 = 31.0 (1 dp)

Marion is observing the velocity of a cyclist at different times. After two hours, the velocity of the cyclist is 18 km/h. After

Ilya [14]

Part A:
Express the given number of hours and velocities of the cyclist as ordered pairs. The time (number of hours) can be our abscissa (x-coordinate) and the velocities can be our ordinate (y-coordinate). The coordinates are therefore (2, 18) and (4, 4). The equation that can be formed in this is established through the two-point equation.

(y - y₁) = ((y₂ - y₁)/(x₂ - x₁))(x - x₁)

Substitute the known variables.
(y - 18) = ((4 - 18)/(4 - 2))(x - 2)

Simplifying the equation,
y - 18 = -7(x - 2)
y = -7x + 32

ANSWER: y = -7x + 32

Part B: This can be graph in the Cartesian plane and numbers 1 to 8 can be substituted to y and take note of the ordered pairs for each point. The slope of the line should be -7 and the y-intercept is 32.
