The pet has 20 guinea pigs and plans to put a pair of guinea pigs in each cage. If the pet store has 8 cages how many more cages will the pet store need?

2 more cages

Step-by-step explanation:

A pair of guinea pigs means , 2 guinea pigs per cage

If the pet store has 8 cages how many more cages will the pet store need?

For 8 cages

1 cage = 2 guinea pigs

8 cages = x

Cross Multiply

x = 8 × 2 guinea pigs

x = 16 guinea pigs

The pet store has 20 guinea pigs

The amount of guinea pigs left

= 20 - 16

= 4 guinea pigs

2 guinea pigs = 1 cage

4 guinea pigs = x

Cross Multiply.

2x = 4

x = 4/2

x = 2 cages

Therefore, the pet store needs 2 more cages

the answer is 175.4379

step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
