The perimeter and area of this minor circle are equal to 32.857 units and 88.345 units² respectively.
<h3>How to calculate the perimeter of the minor circle?</h3>
First of all, we would determine the circumference of this circle by using this formula:
C = πD
C = 22/7 × 14
C = 44 units.
For the length of an arc of the circle:
Arc length/Circumference = 3/7
Arc length = 3/7 × C
Arc length = 3/7 × 44
Arc length = 18.857 units.
Now, we can calculate the perimeter:
Perimeter = 2r + arc length
Perimeter = 2(14/2) + 18.857
Perimeter = 14 + 18.857
Perimeter = 32.857 units.
<h3>The area of the minor circle.</h3>
Mathematically, the area of a minor circle is given by this formula:
Area = θr²/2
But, we would have to find the angle in radians:
18.857/32.857 = θ/360
θ = 3.6059 radians.
Substituting the given parameters into the formula, we have;
Area = (3.6059 × 7²)/2
Area = 88.345 units².
