Four circles, each with a radius of 2 inches, are removed from a square. What is the remaining area of the square?
garri49 [273]

<u>Given</u>:

Given that the radius of the circle is 2 inches.

We need to determine the area of the remaining square.

<u>Area of a square:</u>

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.

<u>Area of the four circles:</u>

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

<u>Area of the remaining square:</u>

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.

I JUST NEED HELP ASAP HELP ME FAST PLZ ILL GIVE YOU BRAINLIST AND 5 STARS
artcher [175]
A:
add up all the money he deposited
3.98+51.02+38.52+12.70=$106.22
and all the money withdrew:
-5.23-5.22-3.50-4.39=-18.34

b-
3.50, 3.98, 4.39, 5.22, 5.23, 12.7 38.52 51.02
just look at the digits from left to right the bigger they are the bigger the number is.if they were equal look at the next digit:
example:
3.50 and 12.7
there is a 1 in 12.7 tenth place but 3.50 doesn't even have a tenth place(or rather, it has a zero on it's tenth place) so 12.7 is bigger than 3.50

c-add all deposits and subtract all withdrawals:
106.22+98-18.34=185.88

ABD and CBD form a linear pair . if m ABD = 6x-12 and m CBD = x + 31 find the m ABD
otez555 [7]

Answer:

m∠ABD = 126°

Step-by-step explanation:

if both angles make a linear pair then their sum equals to 180°

you can solve for x

m∠ABD + m∠CBD = 180

6x-12 + x+31= 180

7x + 19 = 180

7x = 161

x=23; now solve for

m∠ABD = 6x - 12 = 6(23) - 12 = 126°
