Answer:

Step-by-step explanation:

If the circumference of the circle is x cm the perimeter of the square will be 38-x cm.

The area of the square = (38-x)^2.

The radius r of the circle = circumference /2π = x / 2π.

The area of the circle = πr^2 = π * (x / 2π)^2

= x^2/ 4π.

So total area A = (38 - x)^2 + x^2/4π

A = 1444 - 76x + x^2 + x^2/ 4π

A = x^2 - 76x + 0.07958x^2 + 1444

A = 1.07958x^2 - 76x + 1444

X+1/2(x-4)=1/2x+6(x-2)

Andrej [43]

Answer:

B) 1

Step-by-step explanation:

x+1/2(x-4)=1/2x+6(x-2)

x+1/2x-4/2=1/2x+6x-12

x+1/2x-1/2x-2=6x-12

x-2=6x-12

x-6x-2=-12

-5x-2=-12

-5x=-12+2

-5x=-10

5x=10

x=10/5

x=2

If the circumference of a circle is about 15.4 cm, estimate to the nearest whole number the diameter of the circle

nasty-shy [4]

The nearest whole number the diameter of the circle is 5.0 cm.

<u>Given the following data:</u>

Circumference of a circle = 15.4 cm

To estimate to the nearest whole number the diameter of the circle:

In this exercise, you're required to solve for the diameter of a circle and round up its value to the nearest whole number.

<h3>How to calculate the circumference of a circle.</h3>

Mathematically, the circumference of a circle is given by the formula:

$Circumference = \pi D$

<u>Where:</u>

D is the diameter of a circle.

Making D the subject of formula, we have:

$D =\frac{circumference}{\pi}$

Substituting the given parameters into the formula, we have;

$D =\frac{15.4}{3.142}$

D = 4.90 cm

To the nearest whole number:

D = 4.90 ≈ 5.0 cm

The number of men in a tour group is 15 times the number of women. If there are 48 people in the group, how many are men?

Nata [24]

M + w = 48
m = 15w

15w + w = 48
16w = 48
w = 48/16
w = 3

m = 15w
m = 15(3)
m = 45 <==== there r 45 men
