Circumference of a circle is 6.25 what is the area

Mathematics
1 answer:
Pavlova-9 [17]3 years ago
8 0
As we know,
Area of a circle= pi r.r
circumference of a circle= pi.d
so 6.25= pi.d
6.25= 2pi.r
r= 6.25/2pi= 0.99
so now
Area= pi.r.r = 3.14(0.99)(0.99) = 3.077 Answer.

15 / 3 = 5

Take the product and multiply that by the second ratio to find the missing ratio:

9 x 5 = 45

Riley wants to predict a soccer team's number of wins. She considers the number of goals scored by the team's top scorer during
Phoenix [80]

Answer:

b) y=1/3x+5

Step-by-step explanation:

Without the actual scatter plot we would need to deduce from the options provided which would closely model the data. Since the number of goals scored in a game can only be 0 or positives then we can remove options a) and c) since a value of x = 0 would output a negative value to y. That leaves us with options b) and d). Since we know that soccer games vary in the number of goals then we can remove option d) since it represents a steady trend line of 4. Finally, we are left with option b) as the answer.

the graph shows the number of wimbledon championships of several countries. Write the ration that compares the championships won
arlik [135]

Answer:

The ratio that compares the championships won by Australia to the total number won by the United States is equal to \frac{2}{5}

Step-by-step explanation:

Observing the graph

we know that

The championships won by Australia are 6

The championships won by the United States are 15

To find out the ratio, divide the championships won by Australia by the total number won by the United States.

so

\frac{6}{15}

Simplify

Divide by 3 boths (numerator and denominator)

\frac{2}{5}

Convert to percentage

\frac{2}{5}=0.40*100=40\%

that means

For every 2 championships won by Australia the United States won 5

or

The championships won by Australia are 40% of the championships won by the United States
