The first thing you need to do is find the radius of the semicircle. To do that you look to see that the width of the rectangle is the same as the radius. Once you have the Area of a Semicircle calculated multiply it by 3. then, we know that the other length of the rectangle is 3 diameters of a semicircle this means that you multiply the radius of 7 by 6 which gives you 42. You take the area of the rectangle (294) and subtract the area of the 3 semicircles(230.79) Which gives you the answer of 63.21cm^2
Answer:
$12.95 is the final cost for the oranges
$12 is the cost for apple
Step-by-step explanation:
The final cost for the orange is
30/100 x 18.50
=5.55
18.50-5.55
=$12.95
Answer:
Yes
Step-by-step explanation:
It is symmetrical on the y-axis so must be.
Answer:
10 units long
Step-by-step explanation:
We need to find the distance from the origin (0, 0) to the point (-3, -4), that will be a radius of the circle.
Use the distance formula: d = √[(x2 - x1)² + (y2 - y1)²]
Plug in the values from the 2 points we are given...
d = √[(-3 - 0)² + (-4 - 0)²]
d = √[(-3)² + (-4)²]
d = √[ 9 + 16 ]
d = √25
d = 5
The radius is 5, therefore the diameter is 10. (the diameter is always twice the length of the radius)
