Answer:

B) -420

Step-by-step explanation:

Step 1: Plug in 432 as the w variable. Then, the equation becomes 3√4(432) - 432.

Step 2: Multiply 4 and 432 together. The product should be 1,728.

Step 3: Find the cubic root of 1,728. 3√1,728 is 12.

Step 4. Subtract 432 from 12. 12 - 432 is -420.

Answer:

The volume of the pyramid is $1,260\ cm^{3}$

Step-by-step explanation:

we know that

The volume of the triangular pyramid is equal to

$V=\frac{1}{3}BH$

where

B is the area of the triangular base

H is the height of the pyramid

step 1

Find the area of the base B

$B=\frac{1}{2}bh$

we have

$b=14\ cm$

$h=18\ cm$

substitute

$B=\frac{1}{2}(14)(18)=126\ cm^{2}$

step 2

Find the volume

we have

$B=126\ cm^{2}$

$H=30\ cm$

substitute

$V=\frac{1}{3}BH$

$V=\frac{1}{3}(126)(30)=1,260\ cm^{3}$

Find the area of the circle. Round your answer to the nearest hundredth.<br> 3 in.

Vilka [71]

Answer:

28.27 in²

Step-by-step explanation:

The area of a circle is dependent on only one variable: the radius:

A = πr²

If the radius is 3 inches, as you seem to indicate, then:

A = π(3 in)² = 9π in² = 28.27 in²
