Step-by-step explanation:
step 1
Find the area of the circle
The area of the circle is
we have
----> the radius is half the diameter
substitute
step 2
Find the area of a sector
Remember that
The area of the circle subtends a central angle of 360 degrees
so
using proportion
Find out the area of a sector with a central angle of 108 degrees
assume
substitute
4x10^7 The number of zeros the given number has would be the exponent
Let’s remember the most basic thing in percentages, the equation.
Percent x Whole = Part.
We know the whole, and the part, but we are trying to find the percent, so we have to divide the two, first turn your whole and part into a decimal.
Percent x 0.4 = 0.18, so we divide 0.18 by 0.4
0.18/0.4 = 0.45
0.45 = 45%
