First take the inside diameter and divide by 2 to get the radius (4cm)
Then use \pir^2 with 'r' being your radius to get the area of the base
The area is 12.7 cm
Now multiply the height by the area of the base to get the volume/ capacity!
40cm x 12.7cm (rounded to the nearest tenth) = 502.7 cubic centimeters

A rod was cut into 3 piece the length of the 3 piece are in the ratio of 5 : 3 :2 if the shortest is 25cm how long was the rod ​
Vesnalui [34]

Answer:

125 cm

Step-by-step explanation:

<u>Ratio of pieces of the rod:</u>

  • 5:3:2

<u>In total, the rod is equal to:</u>

  • 5x+3x+2x= 10x

<u>Since the shortest peace:</u>

  • 2x = 25 cm,

<u>Length of the rod:</u>

  • 10x = 5* 2x = 5* 25 cm = 125 cm

A student begins a proof of the law of cosines. His work is shown.
Phoenix [80]

The student made an error in <u>step 3</u>. To correct this error, he should define <u>side AY</u> in terms of <u>angle X</u>. <u>Pythagorean theorem</u> relates sides x, y, z, and <u>angle X</u>

<h3>The law of cosine.</h3>

In Trigonometry, law of cosine (cos) is given by this mathematical expression:

cosθ = Opp/Hyp

<u>Where:</u>

  • Opp is the opposite side of a right-angled triangle.
  • Hyp is the hypotenuse of a right-angled triangle.
  • θ is the angle.

In this scenario, we can logically deduce that the student made an error in <u>step 3</u>. To correct this error, he should define <u>side AY</u> in terms of <u>angle X</u>.

After correcting this error, the student can use the <u>Pythagorean theorem</u> to relate sides x, y, z, and <u>angle X</u>.

What symbol compare fractions 5/7 1/13
Kitty [74]

Answer:

5/7 > 1/13. Hence Greater than Symbol will be used to compare the fractions.

Step-by-step explanation:

Given:

Two fractions given are 5/7 and 1/13

We will first calculate each of the fraction and then we will decide which one is greater and which one is smaller accordingly we will assign the symbol for the same.

First we will find the answer for 5/7.

Now dividing the number 5 from 7 we get;

5/7= 0.714

Now we will find the answer for 1/13

Now dividing the number 1 from 13 we get;

\frac{1}{13}= 0.076

From above we can see that 0.714 is greater than 0.076.

Hence we can say that 5/7 is greater than 1/13.

So the symbol used will be greater than > where number 5/7 is greater than 1/13

5/7 > 1/13
