Answer:
32d
Step-by-step explanation:
-The students ride their bikes to and from school every day. The distance is thus;
-Taking that there are 5 school days per week and that it rains in one per week. the total number of days is:
Now, we multiply the distance per day by the total number of days:
Hence, the total distance in a 4-week period is expressed as 32d ( where d is the distance from home to school).
The answer is: [C]: 61.38 cm .

300 = (3.14) * r² ;
______________________
Divide each side by "3.14" ;
r² = 300/3.14 ;
r² = 95.5414012738853503 ;
√r² = √(95.5414012738853503) ;
r = 9.7745281867661188048
Circumference, "C" =
* d ; (d = diameter = 2*r);
C = 2**r ;
C = 2*(3.14)*(9.7745281867661188048)
C = 61.384037012891226094144 ; which rounds to answer choice:
[C]: 61.38 cm .
