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 $ft^2$ .

Brianna and Holden hiked 6 2/9 miles on Monday and 2 2/3 miles on Tuesday. How many times as far did they hike on Monday as they

spin [16.1K]

Answer:

2 1/3 times as far

Step-by-step explanation:

The ratio of distances is ...

(Monday distance) / (Tuesday distance) = (6 2/9)/(2 2/3)

= (56/9)/(8/3) = (56·3)/(8·9) = 7/3 = 2 1/3

They hiked 2 1/3 times as far on Monday as they did on Tuesday.

12 because 2 divided into 1/6 will be 2 times six because your will flip the reciprocal and you'll get 12
