What is the approximate area of the circle that fits perfectly inside of the square? Use Pi = 3.14 and round to the nearest tent

Pani-rosa [81]

Answer:

$19.625\text{ cm}^2$

Step-by-step explanation:

GIVEN: A square with base $5\text{ cm}$ , a circle that perfectly fits inside square.

TO FIND: Approximate area of circle.

SOLUTION:

Consider the figure attached.

let the radius of circle be $x\text{ cm}$

radius of circle $=\frac{\text{length of base of square}}{2}$

$x=\frac{5}{2}\text{ cm}$

$x=2.5\text{ cm}$

Area of circle $=\pi(radius)^2$

$=3.14\times(2.5)^2$

$=19.625\text{ cm}^2$

Hence the area of circle that perfectly fits inside the square is $19.625\text{ cm}^2$

Taya2010 [7]

Answer:

0.25

Step-by-step explanation:

Given that a recently married couple are planning to have four children. They are equally likely to have a boy as well as a girl.

Let X be the no of boys the couples have. X has two outcomes with p = 0.5

X is binomial with n = no of trials = 4 and p =0.5

the probability that they will have three boys and one girl

= $P(X=3)\\=4C3(0.5)^3(0.5)\\= 0.25$

A system has two linear equations in two variables. The graphs of the equations have the same slope but different y-intercepts.

lesya [120]

<span>A system has two linear equations in two variables. The graphs of the equations have the same slope but different y-intercepts. How many solutions does the system have?
</span><span>
A. 0</span>

They have no solutions because these two lines are parallel. They have the same slope. However, two parallel lines have no solutions because they never intersect.

Hope this helps.
