40% = 32/x
Rewrite using a decimal
.40 = 32 / x
Multiply both sides by x
.40x = 32
Divide both sides by .40
x = 32 / .40
x = 80
Write the full fraction
32/80
Answer 32/80
78.5= (3.14)r^2
25=r^2
5=r
So, the radius of a circle with an area is 78.5 cm^2 is 5 cm^2
V: volume of a cone = (πr²h)/3 = 104.67 in³
π: pi = 3.14
r: radius = 1/2 diameter = [unknown]
h: height = 4 in
V = (πr²h)/3
V = r²(πh)/3
r² = (3V)/(πh)
r² = (3 ×104.67)/(3.14 × 4)
r² = 25
r = √25
r = 5 (but remember the radius is only 1/2 the diameter)
thus . . .

Answer:
The answer to your question is: 2, 4, 5, 1 , 3
Step-by-step explanation:
The first line is the second
(3x² - 6)² - (3x²)² = 36(1 - x)(1 + 1)
The second line is the forth
9x⁴ - 36x² + 36x² - 9x⁴ = 36(1 - x)(1 + x)
The next line is the fifth
36 - 36x² = 36(1 - x)(1 + x)
The next line is the first
36(1 - x²) = 36(1 - x)(1 + x)
The last line is the third
36(1 - x)(1 + x) = 36(1 - x)(1 + x)
