a3) 45
Step-by-step explanation:
all triangle equal to 180
Just as you would do it with any other number.
Write out some of it, then move the decimal point 3 places this way <=== .
Some of pi : 3.14159
Divide by 1,000 : 0.00314159
Answer:
96
Step-by-step explanation:
First we need to know the mean of the Steve's scores on 6 of his tests. Given the six scores as 92, 78, 86, 92, 95, and 91.
Mean = sum of the scores/Total test taken
Mean = 92+78+86+92+95+ 91/6
Mean = 534/6
Mean = 89
If he took the seventh test and the mean score is raised by 1 them the new mean will be expressed as;
New mean = 92+78+86+92+95+ 91+x/7 = 89+1
Where x is the new score. Note that of a new score is added, the total year taken will also change to 7
To get x;
92+78+86+92+95+ 91+x/7 = 89+1
92+78+86+92+95+ 91+x/7 = 90
534+x/7 = 90
Cross multiply
533+x = 90×7
533+x = 630
x = 630-534
x = 96
Hence the score of the seventh test is 96
Answer:
Area = PI * radius^2
radius = Sq Root (Area / PI)
radius = Sq Root (78.5 / PI)
radius = Sq Root (24.9873260654)
radius = 4.9987
radius = 5 (rounded)
