What is the volume of the sphere that has a diameter of 3? use 3.14 for pie

aev [14]

Hey ! there

Answer:

113.04 unit cube

Step-by-step explanation:

In this question we are provided with a sphere having radius 3 units and value of π is 3.14 . And we're asked to find the volume of sphere .

For finding volume of sphere , we need to know its formula . So ,

$\qquad \qquad \: \underline{\boxed{ \frak{Volume_{(Sphere)} = \dfrac{4}{3} \pi r {}^{3} }}}$

Where ,

π refers to 3.14

r refers to radius of sphere

Solution : -

Now , we are substituting value of π and radius in the formula ,

$\quad \longrightarrow \qquad \: \dfrac{4}{3} \times 3.14 \times (3) {}^{3}$

Simplifying it ,

$\quad \longrightarrow \qquad \: \dfrac{4}{3} \times 3.14 \times 3 \times 3 \times 3$

Cancelling 3 with 3 :

$\quad \longrightarrow \qquad \: \dfrac{4}{ \cancel{3}} \times 3.14 \times 3 \times 3 \times \cancel{3}$

We get ,

$\quad \longrightarrow \qquad \:4 \times 3.14 \times 9$

Multiplying 4 and 3.14 :

$\quad \longrightarrow \qquad \:12.56 \times 9$

Multiplying 12.56 and 9 :

$\quad \longrightarrow \qquad \: \pink{\underline{\boxed{\frak{113.04 \: unit \: cube}}}} \quad \bigstar$

Henceforth , volume of sphere having radius 3 units is 113 .04 units cube .

Michaela’s favorite fruit to snack on is the “cotton candy grape.” She has $20 to spend on a gallon of cider that costs $3.50 an

daser333 [38]

Answer:

So, to answer this problem, we first have to get rid of the cider cost.

$20-$3.50=$16.50

Since we have $16.50 left, now we have to see how much cotton candy grapes Michaela can buy.

1 pound- $3.75

2 pound- $7.50

3 pound- $11.25

4 pound- $15

5 pound- $18.75

When Michaela buys 5 pounds of grapes, she gets a cost of $18.75.

Since $18.75 is $2.25 more than $16.50, the only option she can choose is 4 pounds.

When Michaela buys 4 pounds, she will spend $15 and she will still have $1.50 left. (If there is no tax.)

In summary, Micheala can buy 4 pounds of grapes without spending more than the rest of the money after buying cider.

(By the way, I LOVE cotton candy grapes.)

Hope this helps!
