Answer:

\huge\boxed{\sf V = 4778.4\ cm\³}

Step-by-step explanation:

<u>Given:</u>

Height = 27 cm

Radius = 13 cm

<u>Formula:</u>

Volume \ of \ cone \ V = \frac{1}{3} \pi r^2h

<u>Solution:</u>

V = 1/3 (3.14)(13)²(27)

V = (3.14)(169)(9)

V = 4778.4 cm³

\rule[225]{225}{2}

Polygon ABCD has sides with these lengths: , 5 units; , 4 units; , 4.5 units; and , 7 units. The slope of is 5, the slope of is
Dahasolnce [82]
Well, you can start by putting the slopes and lengths on the right side (Where is says slope of A'B'). The slopes will be the same, so Slope of AB is still 5 and Slope of BC is still 0.25. When you get to the lengths, just multiply it by 1.2. The length for Length of CD is 5.4 and Length of AD is 8.4

Here's what it should look like:
Slope of A'B' ⇔ 5
Slope of B'C' ⇔ 0.25
Length of C'D' ⇔ 5.4
Length of A'D' ⇔ 8.4

If the radius of a circle is 12cm, then the diameter is 6cm.<br><br> True or false
melomori [17]

Answer:

False.

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Geometry</u>

  • Radius: <em>r</em>
  • Diameter: d = 2r

Step-by-step explanation:

<u>Step 1: Define</u>

Radius = 12 cm

<u>Step 2: Find diameter</u>

  1. Substitute:                    d = 2(12 cm)
  2. Multiply:                        d = 24 cm

∴ The statement is false and should be 24 cm as the diameter.
