A cone has a radius of 4 units and a height of 6 units. Its volume is (A. 96 / B. 100.48 / C. 301.44 / D. 401.92) cubic units. I
Fed [463]

Answer:

<h2>A cone: B. V = 100.48 cubic units</h2><h2>A cylinder: C. V = 301.44 cubic units</h2>

Step-by-step explanation:

The formula of a volume of a cone:

V=\dfrac{1}{3}\pi r^2H

<em>r</em> - radius

<em>H</em> - height

We have <em>r = 4 u</em> and <em>H = 6 u</em>. Substitute:

V=\dfrac{1}{3}\pi(4^2)(6)=\dfrac{1}{3}\pi(16)(6)=\dfrac{1}{3}\pi(96)=32\pi\ u^3

\pi\approx3.14\to V\approx(32)(3.14)=100.48\ u^3

If the cylinder has the same radius and height as a cone, then the volume of the cylinder is three times larger than the volume of the cone.

Therefore, the volume of acylinder:

V\approx3(100.48)=301.44\ u^3

Why?

The formula of a volume of a cone:

V_{cone}=\dfrac{1}{3}\pi r^2H

The formula of a volume of a cylinder:

V_{cylinder}=\pi r^2H

Therefore

V_{cone}=\dfrac{1}{3}V_{cylinder}\to V_{cylinder}=3V_{cone}

If the radius and height are the same.

if you buy 3.18 lb of grapes for $0.99 per pound and 1.25 lb of peaches for $1.09 per pound and 2.75 pounds of pears for $1 and
Flura [38]

<u>Answer:</u>

$7.78

<u>Step-by-step explanation:</u>

3.18 lb (grapes) x $0.99 = $3.15 (Real answer: 3.1482. Rounded to the nearest cent)

1.25 lb (peaches) x $1.09 = $1.36 (Real answer: 1.3625. Rounded to the nearest cent)

2.75 lb (pears) x $1.19 = $3.27 (Real answer: 3.2725. Rounded to the nearest cent)

$3.15 (grapes total) + $1.36 (peaches total) + $3.27 (pears total) = $7.78 (total bill)

<u>Final Answer:</u>

$7.78

PtichkaEL [24]
For the answer to the question above asking what was the amount of the withdraw if <span>Doris put $4000 in a 2-year cd paying 6% interest, compounding monthly. after 2 years, she withdrew all her money?</span>

First year Interest: I(1) = 4000[(1.005)^12 - 1] = 246.71 = penalty for early withdrawal 
Value after two years: P(2) = 4000(1.005)^24 = 4508.64 

Value after 2 years with penalty: V = 4000(1.005^24 - 1.005^12 + 1) = $4261.93
