GETS BRAINLIEST AND 50 PTS!
FromTheMoon [43]
If the diameter is 3 feet, then the radius is 1.5 feet. Area of a circle = pi * radius squared or A =  \pi r^{2}

A = pi * (1.5)²
A = pi * 2.25
A = 3.14 * 2.25
A = 7.065 ≈ 7.1 

7.1 feet² is your answer.

Find all the zeros of the equation.<br><br> -3x^4 + 27x^2 + 1200 = 0
pickupchik [31]

-3x^4 + 27x^2 + 1200 = 0

factor out -3

-3(x^4 -9x^2 -400)=0

divide by -3

x^4 -9x^2 -400=0

(x^2-25) (x^+16) = 0

x^2-25=0     x^2+16=0

(x-5)(x+5)=0      x^2=-16

x=5   x=-5           x = 4i   x=-4i

Answer:  x=5   x=-5           x = 4i   x=-4i
