Hi There!

<span>A beach ball has a radius of 12 in.. How much air will the beach ball hold? (leave your answer in terms of π)?

</span>Vol = \frac{4* \pi * x^{3} }{3}
<span>
Therefore the answer would be 
</span>V = 2304π cubic inches

Another way is?


V = 4/3πr³
r = 12 in.

V = 4/3π(12 in)³

V = 4/3π(1728 in³)

<span>V = 2304π in³</span>

The inscribed polygon can be square or a hexagon.

<h3>What is polygon'?</h3>

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end.

First,

if we join A to B, B to C, C to D and D to A then a square will be formed.

But, if we join passing through the arc intersecting point then join to B then again join to a line passing through arc intersecting then to D.

A six side figure will obtain named as hexagon.

If we apply the Pythagorean Theorem to the Egyptian knots we can see that 3^2 + 4^2 = 5^23 2 +4 2 =5 2 . Which of the sets of th
pantera1 [17]

Answer:

B) { 51, 149, 140 }

C) { 16, 63, 65 }

Step-by-step explanation:

We need to choose Pythagoras theorem formula

c^2=a^2+b^2

now, we can verify each options

option-A:

a=1

b=1

c=1

now, we can verify formula

1^2=1^2+1^2

1=2

We can see that left side is not equal to right side

so, this is FALSE

option-B

a=51

b=140

c=149

now, we can verify formula

149^2=51^2+140^2

22201=22201

We can see that left side is  equal to right side

so, this is TRUE

option-C

a=16

b=63

c=65

now, we can verify formula

65^2=16^2+63^2

4225=4225

We can see that left side is  equal to right side

so, this is TRUE

option-D:

a=6

b=8

c=11

now, we can verify formula

11^2=6^2+8^2

121=100

We can see that left side is not  equal to right side

so, this is FALSE

Look at the graph shown:
NNADVOKAT [17]
We are going to base the answer off of the y=mx+b form where m represents slope and b represents the y-intercept.

First, we know that b must be -1 because the line hits the y-axis when y is -1
So this leaves us with either the first or second choice

Then we choose two points to find the slope. I am using (0,-1) and (1,2). If you count the boxes, the y-value increases by 3 as the x-value increases by 1. So the slope is 3/1 or 3.

So then we know the answer is y=3x-1

Hope this helps

If 2a+3b=12 and ab=6 find the value of 8a^3+27b^3
Alex17521 [72]
<span>A) 2a + 3b = 12
B) ab = 6 solving for a
B) a = 6 / b then we substitute this into equation A)
</span><span>A) 12 / b + 3b = 12  </span><span>multiplying this by "b"
A) 12 + 3b^2 = 12b
A) 3b^2 -12b +12= 0 dividing by "3"
A) b^2 -4b + 4 = 0
Factoring
(b-2) * (b-2) = 0
b = 2
Since b = 2 then a = 3

</span>NOW, we put these numbers into:
<span>8a^3 +27b^3 </span>
8*3*3*3 + 27*2*2*2
216 + 216
The answer is 512
