To solve for the circumference and the area of a circle, first you must determine the radius.

D = 21 inches
R = 1/2D = 1/2(21) = 10.5 inches.

C = 2pi • r
C = 2(3.14) • 10.5 inches
C = 65.97 inches.

A = Pi • r ^2
A = (3.14) • 10.5^2
A = 346.185 in^2.

The area of a circle is 346.185 in^2.

lutik1710 [3]

Answer:

A)4.1%

Step-by-step explanation:

First you need to add all the payments together to get your total.

1400+300+150+800+300+150+100+100+150+200=3650

Then you cross multiply and divide to get the percentage.

\frac{entertainment}{total} \frac{150}{3650}=\frac{x}{100}

In a basketball game 15 of 20 foul shots that Michelle attempted were successful. What percent of her shots were not successful?
mestny [16]
<u>Work 1:</u>
   Successful Percent:

     15 divided by 20 equals .75
     .75 times 100 is equal to 75
     75%
   Not successful Percent:
     
100% minus 75% equals 25%
     <em>25%</em>
<u>Work 2:</u><u />
     20 minus 15 equals 5
     5 divided by 20 is equal to .25
     .25 times 100 is equal to 25
     <em>25%</em>
