Answer:
254 cm² (to 3 s.f.)
Step-by-step explanation:
Area of shaded region
= area of large circle -area of smaller circle
Radius of large circle= 15cm
Radius of smaller circle= 12cm
Area of shaded region
= π(15²) -π(12²)
= 225π -144π
= 81π
= 81(3.14)
= 254.34
= 254 cm² (3 s.f.)
Answer:
Step-by-step explanation:
This is asking you to write the equation in <em>slope-intercept</em> form:
where:
- m is the slope
- b is the y-intercept
- x and y are any corresponding coordinate points (x,y)
You need to find the slope of the two given points using:
Insert the values:
The slope of the given line is -1. Insert this value into the equation:
Now insert one of the given coordinate points as x and y to solve for b:
The y-intercept is 9. Insert the value:
