Question

help

Answer 1

so first we need to find the radius which is half of the diameter... the formula for circumference is 2 * pi * radius so we need to solve for the radius (r) in the equation
75.36 = 2 * 3.14 * r
r = ?
after you get this you need to plug your radius into the equation for area of a circle which is A = pi * r^2
let me know if this helps!

Answer 2

im confused.

Answer 3

okay so we need to divide 75.36 by 2 and by pi which is 3.14 and we get 12

Answer 4

so 12 is our radius then you can use the formula to solve for area
A = pi * r^2

Answer 5

mhm

Answer 6

so 12 squared (12 x 12) is 144
then we need to multiply that times pi which is 3.14
what do you get?

Answer 7

a

Answer 8

yup you're correct (:
