The radius of the circle is 5.30 cm.

<h3>What is a radius?</h3>

A radius is a line that extends from the center of a circle to any point of the circumference.

To calculate the length of the radius of the circle, we use the formula below.

Formula:

  • A = πr²......... Equation 1

Make r the subject of the equation

  • r = √(A/π).................. Equation 2

Where:

  • A = Area of the  circle
  • r = Radius of the circle
  • π = Pie

From the question,

Given:

  • A = 88.44 cm²
  • π = 22/7

Substitute these values into equation 2

  • r = √(88.44/(22/7))
  • r = √(88.44×7/22)
  • r = √(28.14)
  • r = 5.30 cm

Hence, the radius of the circle is 5.30 cm.

I got 1/81. because u spun the spinner twice i multiplied the regions you are allowed to get by 2 which makes your denominator 18 then you can get the numbers 3 and 6 twice since the spinner is used twice then multiplied them together. so it would be 2/18 x 2/18 = 4/324 which equals 1/81

Find the slope and y-intercept for the table and then write the equation in form y=mx+b. Explain how you got your answer.
poizon [28]

Answer:

y=4x+1

Step-by-step explanation:

to find the slope (m) you have to calculate what rise over run is for you table, in this table rise (y values) go up by 4 every time. so thats the numerator for your slope. the run is how much the x value goes up everytime, it goes up by 1 so the denomenator is 1, this simplifies to 4 so m= 4. the y intercept (b) is the y point where x equals zero so it is 1. x and y are simply variables used when graphing so they have no set values.

jarptica [38.1K]

Answer:

=

Step-by-step explanation:

The fractions are equal because we can simplify 3/6 to 1/3 as their biggest common divisor is 3

and

we can simplify 2/4 to 1/2 as their biggest common divisor is 2

So we are using the common divisor to simplify both fractions to solve this problem.
