What is the volume of a pyramid<br> 4 cm,4 cm by 12 cm
Alenkinab [10]

<u>Answer: </u>

The volume of pyramid with dimensions 4cm , 4cm by 12cm is \bold{64 \mathrm{cm}^{3}}

<u>Solution: </u>

Volume of a pyramid can be found out by using the below formula,

\bold{v = \frac{1}{3} l w h}

where,

v is the volume of pyramid  

l is the length of pyramid

w is the width of pyramid

h is the height of pyramid

from question, given that l = 4 ; w = 4; h = 12

hence the volume of pyramid for the given dimensions is  

v = \frac{1}{3} \times 4 \times 4 \times 12

= 4 \times 4 \times 4

= 64 \mathrm{cm}^{3}                      

So the volume of pyramid is \bold{64 \mathrm{cm}^{3}}

Find the measures of the angles of a triangle if the measure of one angle is twice the measure of a second angle and the third a
guapka [62]

Answer:

<h2><em> 38°, 66° and 76°</em></h2>

Step-by-step explanation:

A triangle consists of 3 angles and sides. The sum of the angles in a triangle is 180°. Let the angle be <A, <B and <C.

<A + <B + <C = 180° ...... 1

If the measure of one angle is twice the measure of a second angle then

<A = 2<B ...... 2

Also if the third angle measures 3 times the second angle decreased by 48, this is expressed as <C = 3<B-48............ 3

Substituting equations 2 and 3 into 1 will give;

(2<B) + <B + (3<B-48) = 180°

6<B- 48 = 180°

add 48 to both sides

6<B-48+48 = 180+48

6<B = 228

<B = 228/6

<B =38°

To get the other angles of the triangle;

Since <A = 2<B  from equation 2;

<A = 2(38)

<A = 76°

Also <C = 3<B-48 from equation 3;

<C = 3(38)-48

<C = 114-48

<C = 66°

<em>Hence the measures of the angles of the triangle are 38°, 66° and 76°</em>
