The crayon balloon is made up of a cone and a cylinder. What is the volume, in cubic inches, of the crayon balloon?
gavmur [86]

Answer:

A. 69.12 in.³

Step-by-step explanation:

Volume of the crayon balloon = volume of the cone + volume of the cylinder

= ⅓πr²h + πr²h

✔️Volume of Cone = ⅓πr²h

r = ½(2) = 1 in.

h = 3 in.

Volume of cone = ⅓*π*1²*3 = 3.142 in.³

✔️Volume of Cylinder = πr²h

r = ½(2) = 1 in.

h = 21 in.

Volume of Cylinder = π*1²*21 = 65.97 in.³

✅Volume of the crayon balloon = 3.14 + 65.973 = 69.115

= 69.12 in.³ (nearest hundredth)

<u>We'll assume the quadratic equation has real coefficients</u>

Answer:

<em>The other solution is x=1-8</em><em>i</em><em>.</em>

Step-by-step explanation:

<u>The Complex Conjugate Root Theorem</u>

if P(x) is a polynomial in x with <em>real coefficients</em>, and a + bi is a root of P(x) with a and b real numbers, then its complex conjugate a − bi is also a root of P(x).

The question does not specify if the quadratic equation has real coefficients, but we will assume that.

Given x=1+8i is one solution of the equation, the complex conjugate root theorem guarantees that the other solution must be x=1-8i.
