Answer:
310.23
Step-by-step explanation:
circumference is radius * 2
to get radius from circumference, divide circumference by 2
18.84 / 2 =9.42
area for circle:
pi * r^2
3.14 * 9.94^2
3.14 * 98.8
310.23
46. 6*3=18 hence x=9*3=27 (ratio is 3:1)
47. x=8 clearly 2:1 ratio.
48.ratio is 1/3 hence, x=9/3=3
49.7:1 ratio. so, x=70
I hope you got the hang of it. so do the last two yourself.
The equation for future value F of principal P over t years at r% interest compounded continuously is
F=Pe^(rt) =>
8000 = 4000*e^(0.04*t)
Solve for t:
e^(0.04t)=8000/4000=2
0.04t=log(2)
t=log(2)/0.04=17.33 (years)
Answer:
A = 1/2h(x +y)
a=1/2h x+1/2h y
a=h+x+y
x=h+y+a
I'm not absutly sure this is right but i gave it my best effort
Hope This Helps!!!
Step-by-step explanation:
<u>This number given in the above question is the square root of 3/10</u> .
First of all ,
we can write 9 as 3²,
and 100 can be written as 10².
⇒ Now when we take the root of this two -
⇒ √ 3²/10²
we get ,
⇒ 3/10
The square root of 9/100 is <u>3/10</u> .
