6 0

Answer:

We know length of one quarter of a circle = 2πr/4 = πr/2

So here we can make the equation for to find thr value of radius r

length of one quarter given = 25 cm

so πr/2 = 25 cm

=> πr = 50 cm

=> r = 50/π cm

So the entire circumference of circle =

2πr

= 2 π 50/π cm

= 100π/π cm (ans)

Here we dont substitute the value of π due to represent the answer in terms of pi.

Hope it helps you

What is the probability that the selected consumer is 35–55 years old or likes crunchicles?
Tju [1.3M]

The probability that the selected consumer is 35–55 years old or likes Crunchicles is 0.444.

Number of people who liked Crunchicles = 121

Number of people who are 35 - 55 years of age = 120

Number of people who are 35-55 years of age or like crunchicles = 121 + 120 - 19

The probability that the selected consumer is 35–55 years old or likes Crunchicles = 222/500 = 0.444.

In December, the average total rainfall in all the deserts together is 0.89 mm. Explain how to use the fiqures from the table to
maw [93]
I know this is late but I can still help answer this....

So we know that in December all the deserts altogether had 0.89 mm of rainfall. Now the chart that you have seems to represent the rainfall in August, so we would need to use addition.
0.19 + 0.17 + 0.1 + 0.24 = 0.70 mm
The rainfall altogether would be 0.70 mm in August. Now we compare the difference, we would need to subtract 0.89 mm (December) with 0.70 mm (August).
0.89 - 0.70 = 0.19 mm
There the difference between the two would be 0.19 mm.

Hope this helps!
