Find the area of the base of the pyramid, then find the area of each side then add the areas. hope this help :)

Sample Response: You would first calculate the area of the base, which is length times width. You would then calculate the area of the faces, which is 1/2 (base times height) and multiply the result by 4 for the 4 faces. Finally, add the area of the base and the areas of the faces.

What is the volume of the prism. 4.1 2.8 5.1

Fed [463]

So, when finding the volume, we would just add up every side, and from the question above, it look like that the numbers that we would be adding are the following above.

$4.1+ 2.8+ 5.1=(11.2)$

The volume would be 11.2

Order the integers from least to greatest 5, -1,3,2,-3

Solnce55 [7]

-1 , -3 , 2, 3, 5 would be your outcome

(The negatives are below "0" so thats why they are the 'least'..and the ones with positive outcomes is above "zero" so that's why they are in labeled as the "Greatest" in this problem)

((All negatives is below "0" and most positives is above "0" ))

A central angle of 62 intercepts an arc length of 90 units what is the radius or the circle? Help ASAP

LuckyWell [14K]

Answer:

l = 90, x = 62, r = ?

arc length is:

l = x · 2πr / 360

90 = 62 · 2πr / 360

360 · 90 = 360(62 · 2πr) / 360

32400 = 389.36r

32400 / 389.36 = 389.36r / 389.36

r = 83.2

Step-by-step explanation:

1. label the values and write down the arc length formula

2. replace the l and x by their values

3. multiply both sides by 360 to get rid of the 360 at the denominator

4. since 360 cancel out 360, you're left with 62 · 2πr. multiply them to be able to solve for r. (you can use 3.14 for pi)

5. divide both sides to get r by itself

The scale from an actual triangle to the drawing at the right is 30:1. The scale from the same triangle to Jorge's drawing of th

djyliett [7]

Answer:

The actual triangle is larger

Step-by-step explanation:

Given

$Scale = Actual Triangle : Drawing$

$Scale = 30 : 1$

$Jorge = 101$

Required

Determine which is bigger

The answer to this question can be extracted from the given scale.

The question says: the scale from the actual triangle to the drawing is 30 : 1.

This implies that;

If Jorge's drawing is 101, then the actual length is 30 * 101 =3030

Since, 3030 > 30, then

We cam conclude that the actual triangle is bigger
