Answer:
113.14 Inches²
Step-by-step explanation:
The area of a sector A contain by the minor arc of a circle is given as
A = Ф°/360 * πr²
Where Ф is the angle formed in the arc, π is a constant given as 22/7 and r is the radius of the circle.
Given that the minor arc is contained by two radii, the angel between them is 90° hence, the area of the arc
= 90/360 * 22/7 * 12²
= 113.14 Inches²
25.1cm
C=2πr
here radius, r=4 cm and π=3.142
Put values in formula.
C=2(3.142)(4)
C=25.1 cm (Rounded to 1 decimal place)
