What is gx and radias?

Answer:

This question is incomplete, it lacks the diagram illustrating the circle and the options. The diagram has been attached. These are the options:

a. 10 pie cm2

b. 16 pie cm2

c. 356 pie cm2

d. 676 pie cm2

The answer is D

Step-by-step explanation:

The area of a circle is calculated by using the formula: πr^2, where r is the radius

According to the diagram in the attachment consisting of two circles; a small circle of radius GY=10cm and a large circle of radius YX=16cm.

Hence, Marco wants to create a new circle by using a radius GX i.e. the length of the line GX, which can be derived by adding GY + YX i.e. 10cm + 16cm = 26cm.

Therefore, GX is 26cm, meaning the radius of Marco's new circle will be 26cm.

To find the area of this new circle, we use the formula: πr^2, where r = radius = 26cm

Hence, Area = π × 26^2

26^2 = 26 × 26 = 676

π × 676

= 676π

Area of new circle= 676π squarecentimetres(cm2)

Jesse is playing a game with a number cube with faces numbered 1 through 6. What is the probability of rolling a number that is
lana [24]

Answer:

The probability of rolling a number that is even and a multiple of 3 is \frac{1}{6}

Step-by-step explanation:

The total possible  outcomes of cube = { 1, 2, 3 , 4 , 5 , 6}

Now, let E: Event of getting an even number and a multiple of 3

So, out of all the outcomes, {6) is the ONLY possible favorable outcome.

\textrm{P(E)}  =\frac{\textrm{Number of favorable outcomes }}{\textrm{Total number of outcomes}}

or, P(E) = \frac{1}{6}

Hence, the probability of rolling a number that is even and a multiple of 3 is \frac{1}{6}

Your friend's swimming pool is in the shape of a rectangular prism, with a length of 25 feet, a width of 8 feet, and a height of
RUDIKE [14]

Answer:

Part a) V=1,000\ ft^{3}

Part b) h=5\ ft

Part c) =718\ gal

Step-by-step explanation:

Part a) What is the volume of your friend's swimming pool?

we know that

The volume of a rectangular prism is equal to

V=LWH

substitute the values

V=(25)(8)(5)=1,000\ ft^{3}

Part b) Your swimming pool is in the shape of a cylinder with a diameter of 16 feet and has the same volume as your friend's pool. What is the height of your pool?

we know that

The volume of a cylinder is equal to

V=\pi r^{2} h

we have

V=1,000\ ft^{3}

r=16/2=8\ ft ----> the radius is half the diameter

substitute and solve for h

1,000=\pi (8)^{2} h

h=1,000/(64 \pi)

h=1,000/(64*3.14)=5\ ft

Part c) While you were on vacation, 6 inches of water evaporated from your pool. About how many gallons of water evaporated from your pool?

remember that

1\ ft=12\ in

so

6\ in=6/12=0.5\ ft

Find the volume of water  for h=5-0.5=4.5\ ft

V=(3.14)(8)^{2}(4.5)=904.32\ ft^{3}

so

the volume of water evaporated is equal to

1,000\ ft^{3}-904.32\ ft^{3}=95.68\ ft^{3}

convert to gallons

remember that

1\ ft^{3}=7.5\ gal

so

95.68\ ft^{3}=95.68*7.5=718\ gal

The formula for volume of a prism is V = Bh.
Misha Larkins [42]

Hello, 3Coli here!

Here is the answer to your question:

The variable B stands for the area of the base.

In this prism, B equals 38.5 in.^2

The variable H stands for height.

In this prism, h is 9 in.

The volume of the prism is 346.5 in.^3

Hopefully, this helps! :D

Good luck with your assignment.
