Not sure what you are asking but if you are looking for the next 3 numbers then multiply 5 by 1.5, 7.5 by 1.5, and 11.25 by 1.5
5 * 1.5 = 7.5
7.5 * 1.5 = 11.25
11.25 * 1.5 = 16.875
16.875 * 1.5 = 25.3125
25.3125 * 1.5 = 37.96875
37.96875 * 1.5 = 56.953125

20 m<br> 12 m<br> 34 m <br><br> Find the surface area of this figure

Ad libitum [116K]

Surface area of the fig is 2350.9 sq m (approx).

Step-by-step explanation:

Given,

Diameter = 34 m

so, radius (r) = 17 m

Height of the cylinder (h) = 12 m

Slant height of the cone (l) = 20 m

To find the surface area of the fig

Surface area of the fig = surface area of cylinder + surface area of cone

Formula

Surface area of cylinder = 2πrh

Surface area of cone = πrl

So,

Surface area of cylinder = 2π×17×12 sq m = 408π sq m

Surface area of cone = π×17×20 = 340π sq m

Surface area of the fig = 408π+340π sq m = 748π sq m

= 2350.9 sq m (approx)

Phil’s age is 7 years more than times Peter’s age. Also, 4 times Phil’s age is 2 years less than twice Peter’s age. If x is Pete

Rom4ik [11]

Answer:

2x-4(x+7)=2

Step-by-step explanation:

Peter's age:x.... twice age:2x

Phil's age:x+7...4times age:4(x+7)

Difference if ages is 2

Hence; 2x-4(x+7)=2

There are 10 golf balls in a rectangular prism. Each golf ball has a diameter of 1.25 inches. Find the volume of the golf balls

lara31 [8.8K]

The answer is D.

The formula for the volume of a sphere is $\frac{4}{3} \pi r^{3}$

You would divide the diameter in half which would give you your radius (r).
Then you plug in the radius value to find the volume of ONE ball.
You would then multiply by 10 to find the volume of TEN golf balls.

D is the closest answer to the volume of ten golf balls

We have a study involving 5 different groups that each contain 9 participants (45 total). What two degrees of freedom would we r

vivado [14]

Answer:

Degree of freedoms F(4,40)

Step-by-step explanation:

Given:

There is a study which is involving 5 different groups that each contains 9 participants (totally 45)

The objective is to calculate the degree of freedoms

Formula used:

Numerator degree of freedom = k-1

denominator degree of freedom=N-K

Solution:

Numerator degree of freedom = k-1

denominator degree of freedom=N-K

Where,

K= number of groups = 5

N= total number of observations

which is given as follows,

N=45

Then,

Numerator degree of freedom = k-1

=5-1

Denominator degree of freedom = N-K

=45-5

=40

Therefore,

Degree of freedoms, F(4,40)
