The volume of sphere is \frac{1372}{3}\pi feet cubed.

Step-by-step explanation:

Given,

Surface area of sphere = 196π square feet

Surface area of sphere = 4πr²

We will find radius of sphere.

4\pi r^2=196\pi

Dividing both sides by 4π

\frac{4\pi r^2}{4\pi}=\frac{196\pi}{4\pi}\\\\r^2=49

Taking square root on both sides

\sqrt{r^2}=\sqrt{49}\\r=7

The radius is 7 feet.

Volume of sphere = \frac{4}{3}\pi r^3

Volume=\frac{4}{3}\pi (7)^3\\\\Volume= \frac{4}{3}\pi *343\\\\Volume = \frac{1372}{3}\pi

The volume of sphere is \frac{1372}{3}\pi feet cubed.

Keywords: volume, surface area

Can someone help me solve this Please

Answer:

  • 523 grams
  • 52 grams

Step-by-step explanation:

To find the initial amount, put 0 where t is in the formula and do the arithmetic.

  A(0) = 523(1/2)^0 = 523(1) = 523

The initial amount is 523 grams.

__

To find the amount remaining after 100 years, put 100 where t is in the formula and do the arithmetic.

  A(100) = 523(1/2)^(100/30) ≈ 523(0.0992123) ≈ 52

About 52 grams will remain after 100 years.

Gala2k [10]

Answer:

The fraction of the book Omarion read over the weekend=3/5

Step-by-step explanation:

Step 1

Determine the initial number of pages in a book that's remaining as follows;

Initial number of pages remaining=9/10 of the book

Step 2

Determine fraction of the book read over the weekend as follows;

fraction read over the weekend=fraction of the remaining read×initial number of remaining pages read

where;

fraction of the remaining read=2/3

initial number of remaining pages read=9/10

replacing;

fraction read over the weekend=(2/3)×(9/10)=3/5

The fraction of the book Omarion read over the weekend=3/5
