Question

It's urgent tommorow is my exam so plz.. I will give u 50 points

Answer 1

Step-by-step explanation:

1.)the length of Arc AB=1/4of the circumference of circle

=1/4×2πr

=1/4×2×22/7×14

=1/2×22×2

=1/2×44

=22cm is the length of Arc

Answer 2

Answer:since quarter of circle.

Hence 360°/4= 90°= π

Step-by-step explanation:

1) S=r× theta =14× π/2 =7π 7× 180= 6120

2) 14+14+6120=6148

3) πr^2 × theta/ 360 = 180×14×14×90/360 =

90×196×90 = 196 ×2π

4) area of triangle is πr^2 = π×14×14=196×π = 196× 90= 17640

5) (3)-(4) = 196 ×2π - 196π = 17640
