Answer:
Radius: 4.2cm
Diameter: 8.4cm
Step-by-step explanation:
Radius is half of the diameter.
In order to find the diameter, you would have to multiply the radius by 2.
In order to find the radius, you would have to divide the diameter by 2.
Let L, W and P denote length, width and perimeter.
L = (2/3)W - 5
The perimeter, P, is 2W + 2L, and this, in turn, is
2W + 2((2/3)W - 5), or 2W + (4/3)W - 10, or
(2 + 4/3)W - 10, or (10/3)W - 10
Hi,
The formula for area of a circle is pi r ^2 so the diameter is 12, therefore the radius is half of that so 6. The answer is 113 km².
