PLEASE HELP AS SOON AS POSSIBLE!!!!WILL GIVE BRAINLY TO CORRECT ANSWER!!!!
Mice21 [21]

Answer:

The correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by \pi

Option D is correct option.

Step-by-step explanation:

The circumference of table top = 24 \pi inches

We need to find area of table top

The formula used to find area is: Area = \pi r^2

We need to find radius of tabletop.

The formula used to find circumference is: Circumference = 2\pi r

Putting value of circumference we can find radius

Circumference = 2\pi r\\24\pi =2\pi r\\r=\frac{24\pi}{2\pi}\\r=12

So, radius of table top = 12

Now, finding the area:

Area = \pi r^2\\Area=\pi(12)^2\\Area=3.14(144)\\Area=452.16\:inches^2

So, the correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by \pi

Option D is correct option.

Answer:

if I read your screen correctly

F radius  =  5 x {10}^{-8 }

Sr  radius   =  2 x  {10}^{-7}

40

Step-by-step explanation:

divide the larger one (Sr) by smaller one (F)

the coefficient = 2/5

the exponent = -7-(-8)

can you get the answer from there, don't forget to simplify

A rectangle has a height of b3 + b2 and a width of b2 + 76 + 4.
zaharov [31]

Answer:

The area is:

{b}^{5}  + 8 {b}^{4}  + 11 {b}^{3} +  4 {b}^{2}

Step-by-step explanation:

To find the area of a rectangle, multiply the width by the height (I'll be using x for b, as it is easier when writing the equations):

a =  ({x}^{ 3}  +  {x}^{2} )( {x}^{2}  + 7x + 4) \\ a =  {x}^{5}  +  7{x}^{4}  + 4 {x}^{3}   \\ +  {x}^{4}   + 7 {x}^{3}  + 4 {x}^{2}  \\ a =  {x}^{5}  + 8 {x}^{4}  + 11 {x}^{3} +  4 {x}^{2}
