Answer:
perimeter of circle=2πr
16=2πr
r=16/2π=8/πcm
now.
area of circle=πr²=π(8/π)²=π×64/π²=64/(22/7)=64×7/22=20.36cm²

Answer:
60 miles is equal to 4.8 inches.
Step-by-step explanation:
To find the answer to this question, we need divide 60 by 25 to find out how much to multiply 2 by so its equal.
60/25=2.4
2*2.4=4.8
60 miles is equal to 4.8 inches.
Hope this helps!
Answer:
0.9544
Step-by-step explanation:
P(-2 < Z < 2) means that Z has mean 0 and standard deviation 2.
P(−2 < Z < 2) = F(2) - F(-2)
Using the Z - table,
F(2) = 0.9772
and F(-2) = 0.0228
Thus,
P(−2 < Z < 2) = 0.9772 - 0.0228 = 0.9544
This means that data within two standard deviation is 95%.
