Question

Measure of an arc of a sector is 90°
it's radius is 7cm
Find the perimeter of the sector​

Answer 1

Hey buddy here is ur answer =

tita=90

so length will be tita/360×2 pie ×r

so it will be 90/360×2×22/7×7

=1/4×2×22

1/2×22

=11

so the length of the arc is 11cm

now perimeter =2r + l

=2 × 7 + 11

=14+11=25cm

pls mark as brainleist :)
