a circular dog pen has a circumference of 78.5 feet. approximate by 3.14 and estimate how many hunting dogs could be safely kept

olasank [31]

Answer:

Step-by-step explanation:

To solve this problem, we need to find the area of the pen, then divide that by the area required by each dog.

The relationship between circumference and radius is ...

C = 2πr

Solving for r gives ...

r = C/(2π)

The relationship between radius and area of a circle is ...

A = πr²

Substituting for r from above gives ...

A = π(C/(2π))² = C²/(4π)

Filling in the given numbers, we find the area of the pen to be ...

A = (78.5 ft)²/(4·3.14) = 490.625 ft²

Dividing the pen area by the area per dog gives the number of dogs the pen can hold:

(490.625 ft²)/(60 ft²/dog) ≈ 8.18 dogs

The pen can safely keep 8 dogs.

What does 3 over 8 simplify to

nirvana33 [79]

To simplify, we need to find a number that can divide both the numerator and denominator equally. Can you find a number that will do this? I can't. So it is already simplified.
