Answer:
28.26
Step-by-step explanation:
The question gives the first three digits of π, which is 3.14, and it gives us the radius, which is 3. So, just substitute them into the formula and you’ll get 3.14(3^2). Solve it and the final answer is 28.26.
Hope this helps! :)
Answer:
The answer to 9 is 358
Step-by-step explanation:
It would be 6.55. You need to square root the 43. Since it’s not even and can’t multiply 2 numbers to get the exact number it’s going to be a decimal.
5 + 8 + 11 + 7 + 12 = 43 total marbles
P(first is red) = 8/43
replace
P(second is blue) = 12/43
P(red,then blue) = 8/43 * 12/43 = 96/1849 <===
