Answer:

56.52 in

Step-by-step explanation:

Circumference Formula: C = 2πr

Since we are given radius <em>r</em> = 9, simply plug it into the formula:

C = 2π(9)

C = 18π

C = 56.5487

Nina [5.8K]

Answer:

There are 28 dolls, 32 balls,  20 cars   for 80 total toys

Step-by-step explanation:

dolls : balls: cars: total

7           8          5    (7+8+5)

7           8           5        20

We have a total of  80  

80/20 = 4

We need to multiply each number by 4

dolls : balls: cars: total

7*4     8*4     5*4      20*4

28       32      20       80


There are 28 dolls, 32 balls,  20 cars   for 80 total toys
