Answer:

The area of the base is about 32 square meters

Step-by-step explanation:

V = pi times r^2 times h which is the formula.

Since the volume is 288, and the height is 9 it is,

288 = pi times r^2 times 9,

288/9 = pi times r^2 times 9/9

32/pi = pi/pi times r^2

10.2 = r^2

The square root of 10.2 is about 3.19

Area formula is pi times radius, r^2

3.19 times 3.19  or 3.19^2 = 10.1761

10.1761 times pi is 31.96 which is about 32 square meters.

I hope this helps!

When sarah was 6 months old, she was 21 inches tall and her head had a diameter of 4.5 inches. now, at 20 year sold, she is 6 ft
pochemuha
Answer: Yes, she could be considered similar to herself at 6 months of age.

In mathematics, the concept of similarity is about proportion relationships. In this problem, we are discussing the relationships between age, height and diameter. We are not discussing the absolute value of the numbers themselves.

For example in Geometry, a very small triangle can be similar to a very large triangle if all the angles of the triangle are congruent. The size doesn't matter.

Solve for x.<br><br> x−1/4=3/8
valentinak56 [21]

<u><em>x=5/8 is the correct answer.</em></u><em>  </em>First you had to simplify from both sides of equation, and it gave us, x+\frac{-1}{4}=\frac{3}{8}. Then you add 1/4 from both sides of equation, and it gave us, x+\frac{-1}{4}+ \frac{1}{4}= \frac{3}{8}+ \frac{1}{4}. And it gave us the answer is<u><em> </em></u><u><em>x=5/8 is the final answer. </em></u>Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

John's birthday is this saturday, in buying materials for the party Vicki notices that plates come in packs of 12, cups come in
Vlad1618 [11]

Answer:

Step-by-step explanation:

So, Vicki wants no left overs whatsoever, which means we have to get all three items to the same number. We first look at 10. We know that 10 will always have a 0 in the one's place, meaning that 8 and 12 have to be multiplied by 5, 10, 15, 20, etc., but they do not need to be multiplied by the same number.

Let's take 8 first. 8 can possibly go up to 40, 80, 120, 160, 200, etc.

Then 12. 12 can possibly go up to 60, 120, 180, 220, 280, etc.

We can see that both numbers have 120 in common, so we shall use that.

We know that we can get 10 to 120 by multiplying 10 by 12, meaning Vicki buys 12 packs of cups.

We know that we can get 12 to 120 by multiplying 12 by 10, meaning Vicki buys 10 packs of plates.

And finally, we know that we can get 8 to 120 by multiplying 8 by 15, meaning Vicki buys 15 packs of utensils.

So, since the question is asking for utensils <em>only,</em> we should say that Vicki buys 15 packs of utensils.
