Can someone help me with this math question WILL GIVE 20 POINTS. By the way it’s not 51.496
GrogVix [38]

Below is the formula for the circumference of a circle

C = 2πr

This question gives us the diameter. To find the radius (r) you would divide the diameter by two like so...

16.4/ 2  = 8.2

Plug what you know into the formula and solve...

π = 3.14

r = 8.2

C = 2(3.14)(8.2)

C = 6.28(8.2)

C = 51.496

In the question it asks to round to the nearest tenth like so...

51.5

Hope this helped!

A sales clerk at a car stereo store works for commission only. If 15% of the people purchase an item where the clerk gets a $3 c
ankoles [38]

Answer:

The expected value per customer = $6.35.

Step-by-step explanation:

The probability for a $3 commission = 15% = 0.15.

The probability for a $5 commission = 30% = 0.30.

The probability for a $8 commission = 55% = 0.55.

So, the expected value per customer = 3(0.15) + 5(0.30) + 8(0.55)

= 0.45 + 1.50 + 4.40

= 6.35.

Hence, the expected value per customer = $6.35.

FIND THE SLANT HEIGHT OF A CONE WHOSE VERTICAL HEIGHT IS 12CM AND BASE DIAMETER IS 10CM
nataly862011 [7]

Answer:

13 cm is the height of the cone

The  vertical height = 12 , the radius = 1/2 * 10 = 5, so:

s^2 = 5^2 + 12^2      where s is the slant height.

x^2 169

s = 13 cm (answer).

is the height of the cone

Step-by-step explanation:

Since the base of a cone is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder. So, the formula for the lateral surface area of a right cone is L. S. A=πrl , where l is the slant height of the cone .

I will give you an example try to understand it

Example) Find the volume of the cone shown. Round to the nearest tenth of a cubic centimeter.

Solution

From the figure, the radius of the cone is 8 cm and the height is 18 cm.

The formula for the volume of a cone is,

V=13πr2h

Substitute 8 for r and 18 for h .

V=13π(8)2(18)

Simplify.

V=13π(64)(18)=384π≈1206.4

Therefore, the volume of the cone is about 1206.4 cubic centimeters.

Note: this is just an example it is not really the answer hope this helps :)
