3 x pi x d
= 3 x 3.14 x 5000
= 47,100 feet
There are 5280 feet in a mile, so
47100/5120 = 8.92 miles

The circumference of the cf the circle
=3.14*5000 feet
=15,700 feet
Pranti jogs around this 3 times'
She runs15,700*3
=47,100 feet

hi,,an prolonged way!! do you extremely propose diameter? or the gap around the lake? The circumference is diverse you be attentive to, so the pi circumstances the radius squared = an prolonged thank you to run interior the morning.

unless this is a trick question its 5000 feet so if she travels around 3 times its 15000 feet.
Unless its a trick question;-)
just kidding
Solution:
C = 3.14 · (5000)
= 15708

15700 yards almost 9 miles
5000x3.14x3=47100 ft
divide it by 3 to get the yards or divide it by 5280 to get miles

C = π .D = π.5000 ft
3C = 15,000 .π ft = 47,123 ft
