Answer:
34,407,615
Explanation : 34 millions 407 thousands 615
The perimeter of a circle is its total circumference, but in this case a semi-circle will measure half the circumference plus its diameter.
If the semicircle measures 8cm then the total circle is 16 cm, and we can calculate its diameter or radius from there. The perimeter is defined as:
p = pi*diameter = 16
diameter = 16/pi = 16/3.14
diameter = 5.1 cm
Therefore the semi-circle perimeter is:
perimeter = semi-circle + diameter = 8 + 5.1 = 13.1 cm
Answer:
x=1 and x=-4
Step-by-step explanation:
Put it into your calculator, go to graph and look at which points it says ERROR.
Answer: 300
You need to change 9% into a decimal so it would be 0.09
Then divide 27 ÷ 0.09 = 300
So 9% of 300 is 27
Answer:
The formula to get the rate R would be:
principal x (1+R)^time = (principle + interest)
=> 3890 x (1 + R)^4 = 5908
=> (1 + R)^4 = 5908/3890
=> (1 + R)^4 = 1.5188
=> 1 + R = 1.11
=> R = 1.11 - 1 = 0.11 = 11%
Hope this helps!
