An oblique cylinder has a radius of 9 centimeters and a volume of 486 cubic centimeters. Use Cavalieri’s Principle to calculate
kotegsom [21]

Using Cavalieri’s Principle, the height of the oblique cylinder with the given volume and base radius is 6cm.

Option A) is the correct answer.

<h3>What is the height of the oblique cylinder?</h3>

From Cavalieri's principle, the volume of an oblique cylinder is expressed as;

V = base area × h

V = πr² × h

Given that;

  • Radius r = 9cm
  • Volume of the oblique cylinder V = 486πcm³
  • Height of the oblique cylinder h = ?

V = πr² × h

486πcm³ = π × ( 9cm )² × h

486πcm³ = π × 81cm² × h

486πcm³ = 81πcm² × h

h = 486πcm³ / 81πcm²

h = 6cm

Using Cavalieri’s Principle, the height of the oblique cylinder with the given volume and base radius is 6cm.

Option A) is the correct answer.

Building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18 \pi18π18, pi m
Ksivusya [100]

the area A of the cross section of the column is (81\pi )m^2 .

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

Here we have , building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18π, pi meters. We need to find What is the area A of the cross section of the column .Let's find out:

We know that  , Circumference of circle = 2\pi r

⇒ Circumference = 2\pi r

⇒ 18\pi= 2\pi r

⇒ \frac{18\pi}{2\pi }= \frac{2\pi r}{2\pi }

⇒ \frac{18\pi}{2\pi }=r

⇒ r=9

We know that area of circle = \pi r^2

⇒ Area= \pi r^2

⇒ Area= \pi 9^2

⇒ Area= 81\pi

Therefore , the area A of the cross section of the column is (81\pi )m^2 .

Answer:

x = -3\frac{11}{20}

Step-by-step explanation:

Convert the mixed fractions to improper fractions;

⇒\frac{-19}{4} = x - \frac{6}{5}  

⇒ \frac{-71}{20} = x   [add 6/5 to both sides]

⇒ x = -3\frac{11}{20}   [convert to mixed fraction]
