Find the volume to the nearest cm3<br> 20 cm<br> 35 cm<br> 12 cm

riadik2000 [5.3K]

Answer: 10380cm^3

Explanation:

Find the volume of half cylinder:

V = (pi x r^2 x h)/2 (I use pi = 22/7 for simplifying)
V = 22/7 x 6^2/2 x 35
V = 22/7 x 36/2 x 35
V = 22/7 x 35 x 18
V = 22 x 5 x 18
V = 1980cm^3

Find the volume of the rectangle:

V = 20 x 35 x 12
V = 240 x 5 x 7
V = 1200 x 7
V = 8400cm^3

Find the volume of the whole shape:

V = 1980 + 8400
V = 10380cm^3

Suppose the height of the pyramid is 20 yards. What is the pyramid's volume?

DedPeter [7]

Answer : The correct option is, (B) 1500 cubic yards.

Step-by-step explanation :

Formula used to calculate the volume of square pyramid is:

$V=\frac{a^2\times h}{3}$

where,

V = volume of pyramid

a = base edge of pyramid

h = height of pyramid

Given:

Base edge of pyramid = 15 yards

Height of pyramid = 20 yards

Now putting all the given values in the above formula, we get:

$V=\frac{a^2\times h}{3}$

$V=\frac{(15\text{ yrads})^2\times (20\text{ yards})}{3}$

$V=1500\text{ yards}^3$

Therefore, the volume of pyramid is 1500 cubic yards.

If you shift the exponential parent function, f(x) = 2^x , right 2 units, what is the equation of the new function?

aev [14]

Answer:

$g(x)=2^{x-2}$

Step-by-step explanation:

<u>Translations</u>

For $a > 0$

$f(x+a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units left}$

$f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}$

$f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}$

$f(x)-a \implies f(x) \: \textsf{translated}\:a\:\textsf{units down}$

Parent function: $f(x)=2^x$

Translated 2 units right: $g(x)=f(x-2)=2^{x-2}$
