THIS IS AREA OF CIRCLES PLS HELPP​

THIS IS AREA OF CIRCLES PLS HELPP

Answers

Answer 1

Answer:

3 ft

Step-by-step explanation:

You are given the area, and the area formula, and you can set them equal to each other:

pi r^2 = 9 pi

Divide by pi on both sides:

r^2 = 9

Find the square root of both sides to get:

r = 3 feet

Answer 2

Answer:

r = 3 ft.

Step-by-step explanation:

In order to solve this problem, you need to substitute the information given into the equation and solve for r. The problem tells us that the area of the circle is 9π ft². We can use this value and substitute it into the equation.

9π = πr²

⇒ 9 = r²

⇒ 3 = r

Therefore, the radius of the circle is 3 ft.

What is the distance to the nearest tenth of a unit between point H ( -4,6 ) and point I ( 2,-3 )

Answers

Answer:

10.81 units

Step-by-step explanation:

Given data

point H ( -4,6 ) and point I ( 2,-3 )

x1= -4

y1=6

x2= 2

y2=-3

The formula for the distance between two points is

d=√((x_2-x_1)²+(y_2-y_1)²)

d=√((2-(-4))²+(-3-6)²)

d= √(2+4)²+(-9)²)

d= √(6)²+(-9)²)

d= √36+81

d=√117

d= 10.81 units

Hence the distance between the points is 10.81 units

The piper family arrived at the campground at the time shown on the clock. I took the family 2 hours and 15 minutes to get to the campground. What time did the family leave their house?

Answers

Answer:

As you included no picture, I do not know the time on the clock. We can however, work with assumed figures which you can then relate to your question.

Assuming the time on the clock was 10:45 am, if the family took 2 hours and 15 minutes to get to the camp ground, simply subtract this from 10:45 to find out what time they arrived.

Subtract the 2 hours from 10am:

= 10 - 2

= 8am

Subtract the 15 minutes from 45:

= 45 - 15

= 30

Put that together:

= 8:30 am

They left their house at 8:30 am using this scenario.

Answer:

[tex]l = 3.66[/tex]

Step-by-step explanation:

Given

[tex]r =1[/tex]

[tex]\theta = \frac{7\pi}{6}[/tex]

Required

The arc length (l)

This is calculated as:

[tex]l= r\theta[/tex]

So, we have:

[tex]l = 1 * \frac{7\pi}{6}[/tex]

[tex]l = \frac{7\pi}{6}[/tex]

So, we have:

[tex]l = \frac{7*3.14}{6}[/tex]

[tex]l = 3.66[/tex]

Step-by-step explanation:

We know that;

x-value = 6

y-value = 7

We also know that by moving 3 units right u will add 3 to the x-value, therefore;

Final x-value = 6 + 3 = 9

Final y-value = 7 (there is no change)

Final coordinates: (9, 7)

∠E and ∠F are vertical angles. If m∠E=(5x+55)° and m∠F=(11x-53)°, find m∠E

Answers

Answer:

145° = m∠E

Step-by-step explanation:

Vertical Angles: always congruent, therefore, to find Angle E first find "x" ;

5x + 55 = 11x - 53

55 = 6x - 53

108 = 6x

108/6 = x

18 = x

Now that we know x-value is 18, u can substitute that in for the equation for Angle E for "x";

=> 5(18) + 55 = m∠E

=> 145° = m∠E
