Question

The circumference of a planet is about 26,000 miles. Find its diameter to the nearest mile.

Answer 1

Circumference = (pi)(diameter).

So substitute and solve.

Answer 2

i keep working it out to be 81640? what am i doing wrong?

Answer 3

what did you do to get 81640?

Answer 4

took half of the circumference multiplyed by 2 then by pi

Answer 5

how do i get the diameter? first?

Answer 6

26000 = 3.14(d)
so solve for d.

Answer 7

That's where you went wrong.

Circumference = (pi) x (diameter)

26,000 = (pi) x (diameter)

To find diameter, divide both sides of ther equation by (pi), so you get

diametr = 26,000/(pi) = 8,276 to the rearest mile.

Answer 8

nearest*

Answer 9

nice one thanks for clearing that up!
