Answer:

530.66mm²

Step-by-step explanation:

Area of a circle = $\pi r^{2}$

r(radius) = 13mm

Area = (3.14 × 13²)mm²

= (3.14 × 13 × 13)mm²

= (3.14 × 169)mm²

= 530.66mm²

Hope this helps :))

If you roll a six-sided die, what is the probability you will obtain greater than a 2?

Delvig [45]

If we will roll a fair die then the outcomes wil be 1,2,3,4,5,6.

Hence, the total number of events= 6

3,4,5 and 6 are greater than 2.

So, there's 4 events which are greater than 2.

Now the formula to find the probability is:

probability= $\frac{Number of events more than 2}{Total number of events.}$

= $\frac{4}{6}$

= $\frac{2}{3}$

So, the probability of getting greater than a 2 is 2/3.

Classify 8 and 0.25 rational, integers, or whole number pls

Eddi Din [679]

8 and .25 are rational numbers because integers are negative and whole numbers don't include decimals and rational numbers can include whole number like 8 or 8/1 and .25.
