a container for a hanging plant is a half sphere with a diameter of 9 inches. about how much soil does the container hold
stich3 [128]

Answer:

190.9 in³

Step-by-step explanation:

Whenever one is asked to find how much(quantity of something) a certain container can hold,all you need to understand is that you are been asked about the volume of that container

We all know that the volume of a sphere is 4/3 × 22/7 × r³

And since we are dealing with a container in the shape of half a sphere,the volume of that container will now be volume of a sphere divided by 2

If the formula that was given initially was divided by 2,the new formula will look like this:

4/6 × 22/7 × r³

And we have the diameter but not the radius and we know that to find the radius, all we need to do is to divide the diameter by 2

That is 9/2 = 4.5

Putting the values in the formula,we can now derive the volume of that sphere

4/6 × 22/7 × 4.5³

= 190.9 in³ of soil

melisa1 [442]

Answer:

  350 inches

Step-by-step explanation:

The 7 "ratio units" represent 490 inches, so each represent 490/7 = 70 inches. Then 5 "ratio units" will represent 5×70 inches = 350 inches.

  smaller perimeter : larger perimeter

  = 5 : 7

  = (350 inches) : (490 inches)

What is the value of a1 of the geometric series? Sigma-Summation Underscript n = 1 Overscript infinity EndScripts 12 (negative o
Sliva [168]

Answer:

a_1=12

Step-by-step explanation:

Assuming the geometric series is

$\sum_{n=1}^{\infty} 12*(-\frac{1}{3} )^{n-1}$

then nth term is

a(n)=12*(-\frac{1}{3} )^{n-1},

and the first term is found when n=1:

a_1=12*(-\frac{1}{3} )^{1-1}=12*(-\frac{1}{3} )^0\\\\\boxed{a_1=12}
