Find the radius of a circle so that its area and circumference have the same value

1 answer:

7 0

Area = pir^2
Circumference = pi * diameter
You can cancel out pi since both equations have it; now if r^2=d then r has to be 2 as 2^2=4 and d=2r so if r is 2 d=2(2) = 4

What is the fraction and the percent of the shaded part in each square?

elena-14-01-66 [18.8K]

Answer:

Part a) The fraction is $\frac{5}{9}$

Part b) The percent is $55\frac{5}{9}\%$

Step-by-step explanation:

Part a)

Find the fraction

we know that

To find the fraction of the shaded part in the square divide the number of shaded squares by the total number of squares

Let

x-------> the number of shaded squares

y-------> the total number of squares

f-------> the fraction of the shaded part

$f=\frac{x}{y}$

In this problem we have

$x=20\ shaded\ squares$

$y=36\ total\ squares$

substitutes

$f=\frac{20}{36}$

Simplify

$\frac{20}{36}=\frac{5}{9}$

Part b) Find the percent

To find the percent multiply the fraction by 100

$\frac{5}{9}*100=\frac{500}{9}\%$

convert to mixed number

$\frac{500}{9}=\frac{495}{9}+\frac{5}{9}=55\frac{5}{9}\%$

Identify the sequence as arithmetic geometric or neither -8, -3, 6, 11, -22

melomori [17]

Answer:

Neither

Step-by-step explanation:

Check if it's arithmetic:

-8, -3, 6, 11, -22

+5 +6 +5 -33

Nope

Check if geometric:

-8, -3, 6, 11, -22

*3/8 *-2 *11/6 *-2

Nope

So it's neither
