Answer me for the five questions pls
Answers
Answer:
→ Area of a quadrant, A= (πr2)/4 Square
unit
→ Length of the Arc = s = r \theta, where,
s = arc lengthr
r = radius
\theta = central angle in radians
→ The area of a sector of a circle is =
½ r² ∅, where,
r = the radius
∅ = the angle in radians subtended by the arc at the centre of the circle.
→ The perimeter of a semicircle = 1/2(πd)+ d
or πr + 2r, where,
r = the radius.
→ Perimeter of a quadrant of a circle =
(π2 + 2)r
