The goat is tied in the four corners of an 8-foot by 4-foot pump house. The rope is 8 feet. The goat is eating the grass, forming a circle The pattern is 3/4 of a circle radius 8 and 1/4 of a circle radius 4.

Getting the area of radius of 8 feet
Area = pi * r^2
Area = pi * 8^2
Area = 201.06 feet^2

Getting the area of radius of 4 feet
Area = pi * r^2
Area = pi * 4^2
<span>Area = 50.27 feet^2
</span>
3/4 of 201.06 = 150.80 feet ^2
1/4 of 50.27 = 12.60 feet^2

So the total area is 153.40 feet^2

Which of the following represents "four times the square of a number is thirty-six"?

Lapatulllka [165]

Answer:

Option (b) is correct.

$4x^2=36$

Step-by-step explanation:

Given expression "four times the square of a number is thirty-six"

We have to write it mathematically and choose the correct options out of given options.

Consider the given expression "four times the square of a number is thirty-six"

Then

let the number be x ,

Then four times the square of a number written mathematically as $4x^2$

And given "four times the square of a number is thirty-six" written mathematically as $4x^2=36$

Therefore, "four times the square of a number is thirty-six" written mathematically as $4x^2=36$

Option (b) is correct.
