Area of a Circle Formula: A = πr²

  • <em>r</em> is radius

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>r</em> = 6.5 m

<u>Step 2: Find Area</u>

  1. Substitute in variables [Area of a Circle Formula]:                                         A = (3.14)(6.5 m)²
  2. Evaluate exponents:                                                                                         A = (3.14)(42.25 m²)
  3. Multiply:                                                                                                             A = 132.732 m²
  4. Round:                                                                                                               A ≈ 132.73 m²

Which values from the given replacement set make up the solution set of the inequality?
ziro4ka [17]
8,9,10
how i found this out was if u replace m with 8 it will be 8+7 which is 15 and less then 18
for 9 its 9+7 which is 16 which is less then 18
and for 10 its 10+7 which is 17 which is less then 18
and for 11 its 11+7 is 18 which is equal to 18 so it would not apply to this equation
hope this helps

Find the location of the x-intercept, the location of the y-intercept, and the slope for the line
I am Lyosha [343]

Answer:

x intercept  (15/4,0)

y intercept (0,2)

slope 8/15

Step-by-step explanation:

15y − 8x = 30.

To find the x intercept, set y =0

15(0) -8x = 30

8x = 30

Divide each side by 8 to solve for x

8x/8 = 30/8

x = 15/4

To find the y intercept, set x =0

15y -8(0) = 30

15y = 30

Divide each side by 15

15y/15 = 30/15

y =2

To find the slope we solve the equation for y

15y − 8x = 30.

Add 8x to each side

15y − 8x+8x =8x +30.

15y = 8x +30

Divide each side by 15

15y/15 = 8x/15 +30/15

y = 8/15x +2

The slope is 8/15
