Four circles, each with a radius of 2 inches, are removed from a square.

natka813 [3]

Given:

Given that the radius of the circle is 2 inches.

We need to determine the area of the remaining square.

Area of a square:

Given that each circle has a radius of 2 inches.

Then, the diameter of each circle is 4 inches.

Hence, the side length of the square is 2 × 4 = 8 inches.

The area of the square is given by

$A=s^2$

$A=8^2$

$A=64$ $in^2$

Thus, the area of the square is 64 square inches.

Area of the four circles:

The area of one circle is given by

$A=\pi r^2$

Substituting r = 2, we have;

$A=4\pi$

Thus, the area of one circle is 4π in²

The area of 4 circles is 4 × 4π =16π in²

Hence, the area of the 4 circles is 16π in²

Area of the remaining square:

The area of the remaining square is given by

Area = Area of the square - Area of four circles.

Substituting the values, we get;

$Area=64-16\pi$

Thus, the area of the remaining square is (64 - 16π) in²

Hence, Option c is the correct answer.

One number is one more than a second number. Five times the first is 3 less than 6 times the second. Find the numbers.

TiliK225 [7]

The value of the first number is 9 , and

the value of the second number is 8 .

In the question ,

statements about two numbers is given ,

let the first number be x ,

let the second number be y .

According to the first statement " One number is one more than a second number "

translating it into the equation form , we get

x=y+1 ...(i)

According to the second statement which states " Five times the first is 3 less than 6 times the second "

translating it into the equation form , we get

5*x = 6*y - 3

5x = 6y - 3

Substituting the value of x from equation (i) , we get

5(y+1) = 6y - 3

5y + 5 = 6y - 3

6y-5y = 5+3

y = 8 ,

substituting y=8 in the the equation (i) ,

x = 8 + 1

x = 9

hence the first number = 9 and the second number = 8 .

Therefore , the value of the first number is 9, and

the value of the second number is 8 .
