The answer is a 36 + 15 + 15+ 15 +15

Answer:

a. 36+15+15+15+15

Step-by-step explanation:

The base of the pyramid is a square. We know that all sides of a square are equal so if we multiply the two sides of the base square(6*6) we get 36.

The area of a triangle can be found with the formula (b*h)/2. If we input the given values of 5 and 6 into our equation, then (5*6)/2 is 15 and since there are 4 triangles in the square pyramid, you multiply 15 by 4 (or add 15+15+15+15), and add the 36 from the base square.

Hope this helps :)

tresset_1 [31]

Answer:

Step-by-step explanation:

The volume of a cylinder can be determined using the formula V = Bh where B is the area of the base of the cylinder and h is the height.

Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.

In the real world, calculating volume is probably not something that you will use as often as calculating area.

However it can still be important. Being able to calculate volume will enable you to, for example, work out how much packing space you have when moving house, how much office space you need, or how much jam you can fit into a jar.

It can also be useful for understanding what the media mean when they talk about the capacity of a dam or the flow of a river.

Jasmine is riding on a carousal. She is sitting 9.5 feet from the center and it takes 20 seconds to
rusak2 [61]

Answer:

<em>2.983 </em>ft/sec

Step-by-step explanation:

Given that

Distance between center and Jasmine riding on a carousal = 9.5 feet

Time taken to complete one rotation = 20 seconds

To find:

Jasmine's linear speed = ?

Solution:

Number of revolutions per minute = \frac{60}{20} = 3

Formula for linear speed is given as:

v=\dfrac{2\pi}{60}\cdot r\cdot RPM

Where r is the radius of circular path and

RPM is the number of revolutions per minute.

v=\dfrac{2\pi}{60}\times 9.5 \times 3\\\Rightarrow v=\dfrac{\pi}{10}\times9.5 \\\Rightarrow v = \bold{2.983\ ft/sec}

Therefore, the linear speed is <em>2.983 ft/sec.</em>
