Leeann rode her bike 6.75 miles one day and 12.4 miles the next day. How many miles did she ride her bike both days?
amid [387]

Number of miles Leeann rode on Day 1 =6.75 miles

Number of miles Leeann rode on Day 2=12.4 miles

The question is asking us to find the total number of miles she rode in all.

Number of miles Leeann rode on Day 1 and day 2 = 6.75+12.4=19.15 miles.

Number of miles she ride her bike both days is 19.5 miles.

Use either the shell method or the disk/washer method to find the volume of the solid (Calculus Help!!!)
Rufina [12.5K]

Integrating with shells is the easier method.

<em>V</em> = 2<em>π</em> ∫₁³ <em>x</em> (√<em>x</em> + 3<em>x</em>) d<em>x</em>

That is, at various values of <em>x</em> in the interval [1, 3], we take <em>n</em> shells of radius <em>x</em>, height <em>y</em> = √<em>x</em> + 3<em>x</em>, and thickness ∆<em>x</em> so that each shell contributes a volume of 2<em>π</em> <em>x</em> (√<em>x</em> + 3<em>x</em>) ∆<em>x</em>. We then let <em>n</em> → ∞ so that ∆<em>x</em> → d<em>x</em> and sum all of the volumes by integrating.

To compute the integral, just expand the integrand:

<em>V</em> = 2<em>π</em> ∫₁³ (<em>x </em>³ʹ² + 3<em>x</em> ²) d<em>x</em>

<em>V</em> = 2<em>π</em> (2/5 <em>x </em>⁵ʹ² + <em>x</em> ³) |₁³

<em>V</em> = 2<em>π</em> ((2/5 ×<em> </em>3⁵ʹ² + 3³) - (2/5 × 1⁵ʹ² + 1³))

<em>V</em> = 4<em>π</em>/5 (9√3 + 64)
