First triangle sides are 20 and 30. Second triangle sides are 16 and 24. Write the ratio of corresponding sides for the similar triangles and reduce the ratio to lowest terms.

5:4

Step-by-step explanation:

20 and 16 are both divisible by four. 20/4=5 and 16/4=4. 30 and 24 are both divisible by 6. 30/6=5 and 24/6=4. Because these answers match, the ratio of corresponding sides is 5:4.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
