Peter has a unique computer. The screen of the computer is a square and measures twelve inches. What is the area of the entire computer screen?

A. 144 in
B. 124 in
C. 54 in
D. 48 in

Answers

Answer 1

Answer:

A. 144 in

Step-by-step explanation:

Squares have congruent sides.

One side is 12 inches, so all of the other sides are 12 inches.

To find the area of a square, multiply width by height. The width is 12, and the height is also 12

12 * 12 = 144

144 in ^2

Answer 2
A.

If it is 12 inches, the sides are all 12 inches, so simply multiply the height and width so 12 • 12 = 144

So the area is 144 inches

B) 9ft

The area of a square is us found by taking the length of a side and squaring it. For example, if 9 is the side length, we would find the area by doing 9^2 or 9 x 9. This gives us 81 which is the closest to 76.5.

The total number of ski trails based on the information about the fraction is 12 ski trails.

How to calculate the fraction?

The difference in length between the longest ski trail and the shortest ski trail will be:

= 3 1/8 - 2 1/4

= 3 1/8 - 2 2/8

= 7/8 miles

The total length of the ski trials that are 2 7/8 miles long will be:

= 3 × (2 7/8)

= 3 × 23/8

= 69/8

= 8 5/8 miles

The sum of the shortest and longest trail will be:

= 3 1/8 + 2 1/4

= 3 1/8 + 2 2/8

= 5 3/8

Lastly, the longest ski trail isn't more than three times the shortest trail. Therefore, Eli is correct.

Answer:

3 cm

Step-by-step explanation:

[tex]V_{cylinder} = 189\pi \: cm^3[/tex] (Given)

[tex]h_{cylinder} = 21\: cm[/tex] (Given)

Formula for [tex]V_{cylinder}[/tex] is given as:

[tex]V_{cylinder} = \pi r^2h[/tex]

[tex]\implies 189\pi = \pi r^2(21)[/tex]

[tex]\implies \frac{ 189\pi}{21\pi} = r^2[/tex]

[tex]\implies 9 = r^2[/tex]

[tex]\implies \pm\sqrt 9 = r[/tex]

[tex]\implies \pm 3 = r[/tex]

A. 331.24 cm
B. 321.24 cm
C. 74.8 cm
D. 72.8 cm

Answers

Hi!

Answer:

A) 331.24

Step-by-step explanation:

To find the area, you need to multiply LxW, (Length x Width) and in this case, since it's a square, the sides are equal. Each side is 18.2 cm, so all we have to do is multiply 18.2 by 18.2, and then we get 331.24, so your answer is option A.

I hope this helps! :)

It’s A since 18.2*18.2=331.24
