Step-by-step explanation:

Area of shaded region = area of circle - area of rectangle

$= \pi \: {r}^{2} - lb \\ \\ = 3.14 \times {6}^{2} - 7 \times 5 \\ \\ = 3.14 \times 36 - 35 \\ \\ = 113.04 - 35 \\ \\ = 78.04 \: {cm}^{2} .$

FIND THE MISSING DIMENSION! NEED ASAP! TINY SQUARE IS A =3025 in ²

Nata [24]

Answer:

Step-by-step explanation:

Rule: never completely trust a diagram that comes with a geometry question. This is a case in point. The "tiny" square is actually much larger than the "larger" square.

If you are trying to find the length of the sides of the squares, the formula is

Area = side^2

3025 = side^2

Take the square root of both sides.

sqrt(3025) = sqrt(side^2)

To find the square root of 3025, do the following

Press √

type in 3025

type in =

You should get 55.

======================

The second square is done the same way

√

90.75

And you should get 9.526

Recall from Example 1 that whenever Suzan sees a bag of marbles, she grabs a handful at random. She has seen a bag containing th

hammer [34]

Answer:

Required Probability in the lowest terms as fractions = $\frac{15}{182} =0.0824$

Step-by-step explanation:

Step 1:-

Given Suzan has three red marbles, two green ones, five white ones, and two purple ones.

Total marbles = 3R+2G+5W+2P = 12

The number of exhaustive cases that the five marbles drawn from 12 marbles

n(S) = $12C_{5} = 792 ways$

by using formula $n_{Cr_{} } = \frac{n!}{(n-r)!r!} = \frac{12!}{(12-5)!5!}$ = 792

The number of favorable cases

She has drawn two red marbles from 3 red marbles, that is 3c₂ ways

she has drawn one marble drawn from 2 green marbles, that is 2c₁ ways

she has drawn one marble drawn from 5 white marbles, that is 5c₁ ways

she has drawn one marble drawn from 2 purple marbles, that is 2c₁ ways

The favorable cases are (n(E) = 3c₂ X 2c₁X5c₁X2c₁ = 60 ways

Required Probability = $\frac{n(E)}{n(S)}$

$Required probability = \frac{n(E)}{n(S)} = \frac{60}{792}$

Required Probability in the lowest terms as fractions = $\frac{15}{182} =0.0824$

Suppose you cut a square into two rectangles as shown below. Write an expression for the area of the square

Hunter-Best [27]

The area of each rect. would be xy, so the total area of the square would be 2xy, by definition of area of a square
