you need to find the radius of the circle. 

Use the curcumference of circle formula

$$C = 2\pi r$$

in your question you have 

$$50.24 = 3 \times 3.14 \times r$$

you need to solve for r


Once you have found the radius then use the area of a circle formula 

$$A=\pi r^2$$

im lost lol

campbell_st · Answer

ok... can you find the value of the radius from the circumference information 

50.24 = 2 x 3.14 x r
