Answer 2

Step-by-step explanation:

using dark circle as a theta (●)

using dark square as a pi(■)

given,

s(length of an arc)=8.8

●=24 if we convert it in radian then

24×■/180 =2■/15

now using formula,

s( legth of arc)=radius(r)×theta(■)

but we have to find radius

so r=s/2■/15

r= 8.8×15×7÷2×22

r= 924÷44

r= 21

radius we refers for length of penduluit means length of pendulum is 21cm.
