A rectangle has a width of 9 units and a length of 40 units. What is the length of a diagonal? 31 units 39 units 41 units 49 uni
BigorU [14]

Answer:

41

Step-by-step explanation:

So basically you need to use the pythagorean thrm. Essentially, the diagonal and the width and length create a triangle, the diagonal being the hypothenuse. So the formula goes as \sqrt[]{a^{2} +b^{2} }. the variable "a" being the length and the variable "b" being the width.  So plug it in and there you have your answer!

Norma-Jean [14]

Answer:

<u>Use the formula for area of the triangle:</u>

  • A = 1/2bh, where b- base, h- height or altitude
<h3>Part A</h3>

<u>The triangle i has:</u>

  • b = 4 cm, h = 1.5 cm

<u>The area is:</u>

  • A = 1/2*4*1.5 = 3 cm²
<h3>Part B</h3>

Triangles have same area as they are congruent.

<u>Total area is:</u>

  • 3*2 = 6 cm²

A cone has a 4 radius and a 8 height what is the volume
Marta_Voda [28]

Hey there! I'm happy to help!

To find the volume of a cone, you multiply the base by the height and then divide by three.

First, we need to find the base. A cone has a circle for the base. To find the area of a circle, we square the radius and multiply it by pi (we will use 3.14).

4²=16

16×3.14= 50.24

Now, we multiply our base by the height.

50.24×8=401.92

Finally, we divide by three.

401.92÷3≈133.973 (to nearest thousandth)

Therefore, the volume of the cone is about 133.973 units cubed. If you were to use exact pi, it would be more like 134 because of all those decimals after pi!

Now you can find the volume of cones!

I hope that this helps! Have a wonderful day!
