Alex has trained his puppy, Popper, to jump through a ring. According to Alex's measurements and calculations, the ring has a diameter of 3.5 feet. What is the ring's circumference (use 3.14 for pi)?

11 ft

Step-by-step explanation:

The ring takes circular shape and for a circle, circumference is given by

Where C represent circumference and d is the diameter.

Taking use 3.14 for pi as instructed and substituting 3.5 ft for diameter d then

C=3.14*3.5=10.99 ft

Rounding off, this is approximately 11 ft

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
