In terms of diameter (d), the area (A) of a circle is given by
A = (π/4)d²
For your larger circle ...
A = (π/4)*(24 km)²
A = 144π km² . . . . . . . . area of larger circle
For your smaller circle ...
A = (π/4)*(8 km)²
A = 16π km² . . . . . . . . . area of smaller circle
The ratio of the two areas is
(larger area)/(smaller area) = ((π/4)*(24 km)²) / ((π/4)*(8 km)²)
= (24/8)² . . . . . . . . . . . . π/4, km cancel, so it simplifies to this
= 3²
= 9 . . . . . . this many small circles have the same area as the larger circle
Changing km to ft does not change the ratio of areas.
Answer:
55000 is neither a perfect square or cube as it leaves 5 and 11 as remainder
Explanation:
3 : 8
x 4 x4
= 12 : 32
or
It can be written two ways; 3:8 or 12:32. Equivalent ratios (or equivalent fractions) are two ratios that express the same relationship between numbers. We can create equivalent ratios by multiplying or dividing both the numerator and denominator of a given ratio by the same number.
