The Volume of air needed for a spherical balloon of radius 4 inch and circumference 8π is 85.3 cubic inch

<h3>Volume of Sphere</h3>

Given Data

  • Circumference = 8π

Let us find radius

circumference = 2πr

8π = 2πr

8 = 2r

r = 8/2

r = 4 inch

Let us find the volume of the sphere

Volume = 4/3πr^3

Volume = 4/3* π*4^3

Volume = 4/3*π64

Volume = 256π/3

Volume = 85.3 cubic inch

What is the sum of the angle measures in a 16-gon
madreJ [45]

It says to find the sum of the angle measures in a 16-gon.

We have a formula to find the sum of interior angles of polygon with 'n' sides.

Sum = (n-2)·180°

Here the value of n would be 16 for a 16-gon.

So, sum = (16-2) × 180° = 14 × 180° = 2520°

Hence, the sum of the angle measures in a 16-gon is 2520°

In which question is r = -17 a solution?
asambeis [7]

Answer:

None

Step-by-step explanation:

For option A

3-2r/4=10 and combining like terms and re-arranging we obtain

-2r/4=10-3

-2r/4=7

r=7*4/-2=-14

For option B

3/4-2r=10 then combining like terms and re-arranging

-2r=10-3/4

-2r=9 1/4

r=(9 1/4)/-2=-4.625

For option C

3(r-4)=10 dividing both sides by three first

r-4=10/3

r=10/3+4= 7 1/3

For option D

3-r/4=10

-r/4=10-3

-r/4=7

r=7*-4=-28

Therefore, none of the options yields r=-17
