Will fan and medal. how is this correct? 3. a family is building a circular fountain in the backyard. the yard is rectangular and measures 7x by 6x and the fountain is going to be circular with a radius of 2x. once the fountain is build, what will be the area of the remaining yard? a. 38x^2 b. [x] 2x^2 (21 – 2pi) c. 42x^2 – 2pix^2 d. 38pix^2,

Step

Find the area of the rectangular yard

the area of the rectangular yard is equal to

where

L is the length side of the rectangle

W is width side of the rectangle

in this problem we have

Step

Find the area of a circular fountain

we know that

the area of a circle is equal to

where

r is the radius of the circle

in this problem we have

substitute

Step

Find area of the remaining yard

Subtract the area of a circular fountain from the area of the rectangular yard

therefore

the answer is the option B

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
