The volume of a spherical sculpture is 256 ft³. Rhianna wants to estimate the surface area of the sculpture. To do the estimate,

Brrunno [24]

Answer:

192 $ft^2$

Step-by-step explanation:

Given that

Volume of spherical sculpture = 256 ft³

$\pi$ is used as 3.

To find:

Surface area of sculpture = ?

Solution:

First of all, let us learn about the formula for Volume and Surface Area of Sphere:

1. $Volume =\frac{4}{3}\pi r^3$

2. $Surface\ Area = 4\pi r^2$

Given volume is 256 ft³.

$256 = \dfrac{4}{3}\pi r^3\\\Rightarrow 256 = \dfrac{4}{3}\times 3 r^3\\\Rightarrow 256 = 4 r^3\\\Rightarrow r^3=64\\\Rightarrow \bold{r = 4\ ft}$

Now, let us put r = 4 in the formula of Surface Area to find the value of Surface Area:

$Surface\ Area = 4\pi 4^2 = 4 \times 3 \times 16 = \bold{192\ ft^2}$

So, approximate surface area of sculpture is 192 $ft^2$ .

Igoryamba

The answer is D. j - 14 = 28

Basically, saying the answer aloud, you will be saying the jellybeans my mom added to the bag minus the 14 jellybeans I had previously is equal to my total of 28 jellybeans I have now.

Timothy bought 10 cookies for $5.00 let x represent the number of cookies purchased and let y represent the total cost. graph th

Soloha48 [4]

We are given that cost of 10 cookies = $5.

Let us find the cost of one cookie.

Cost of one cookie = 5/10 = $0.5.

Let us assume number of cookies purchased = x cookies.

And total cost of x number of cookies = y.

Therefore,

Cost of x cookies at the rate $0.5 each cookie = 0.5x

Therefore, cost equation would be

y=0.5x.

For 0 number of cookies there would be 0 cost.

So, first coordinate would be (0,0) and we are given 10 cookies cost = $5.00.

Therefore, second coordinate would be (10,5).

Plotting (0,0) and (10,5) coordinates on the graph and jointing the points to draw a line.

The drawn line represents the proportional relationship.
