Step-by-step explanation:

The man and the son form similar triangles, so the lengths of corresponding sides of the triangles are proportional.

6/8 = x/4

8x = 24

x = 24/8

x = 3

Question 15

Triangles SCA and STR are similar, so the lengths of corresponding sides are in proportion.

SA + AR = SR

SA + 3 = 9

SA = 6

SA/SR = SC/ST

6/9 = SC/12

2/3 = SC/12

3SC = 2 * 12

3SC = 24

SC = 8

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24
