Answer:

<u>254.34 in²</u>

Step-by-step explanation:

<u>Area of a circle</u>

  • A = πr²
  1. <u>r = radius of the circle</u>

<u>Solving</u>

  • A = 3.14 x (9)²
  • A = 3.14 x 81
  • A = <u>254.34 in²</u>

Answer:

254.47 in²(rounded to nearest hundredth)

_________________________________________________________

A = \pi r^2

<em>tiny r means radius</em>

<em>² means multiply the number by itself twice</em>

<em />\pi r^2 = \pi * 9^2 = 81\pi(254.47~in^2)

Solve for x<br><br> 15x^2+16x= -4
Klio2033 [76]
15x²+16x+4 =0      (ax² +bx +c=0)

Δ = b²-4ac =256 - 4×15×4 =16

x1 = (-b+√Δ) / 2a = (-16+√16) / 30 =( -16+4) / 30 = -12/30 = - 2/5
x2 = (-b -√Δ) / 2a = (-16 -√16) / 30 = (-16 -4) /30 = -20/30 = -2/3
