Find the circumference of a circle whose area is 60 cm2.
a. 2v157 cm
b. 4/15 cm
c. 307 cm
d. 9007 cm
select the best answer from the choices provided

im pretty sure the answer is b

if you find the circumference using area you get 27.46, if you then solve the answers they provided you can see b, 4v15*pi equals 27. then you just round it and get 27.46.

good luck!

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
