Answer: $91.40
Explanation
137.10/3=45.7
45.7x2=91.4
I think You should break it down to the First and third One because of
The mass should be 75.71 grams
To find density is D = M / V
So you would have to multiply the volume by the density
The circumferince of the circle is 2πR ;
The area of the circle is π

;
Then, 2πR = 704 ;
R = 352 / π ;
π

= π × ( 352 / π )^2 = ( 352^2) / π = 123904 / π ≈ 39459.87 ≈ 39460 cm^2 ;
