Answer:
The diameter is 9.252 :)
Step-by-step explanation:
From the given diameter, get the radius. The perimeter of a semicircle is half the perimeter of a circle, but we excluded the base. So, the perimeter now is:
2πr+2r
Put the value of radius in the formula and get the answer wich is 9.252!

Answer:the answer is B
Step-by-step explanation:
Answer:
50.27in
Step-by-step explanation:
Given data
Diameter of small tire= 13in
Radius= 13/2= 6.5in
Circumference= 2πr
C= 2*3.142*6.5
C= 40.85 in
Diameter of Big tire= 29in
Radius= 29/2= 14.5in
Circumference= 2πr
C= 2*3.142*14.5
C= 91.118in
Hence the difference in distance between the two tires after on revolution is
=91.118-40.85
=50.27in
Answer:
Option C. \frac{5}{8} is the correct option.
Step-by-step explanation:
In the given question numbers marked on a spinner are given = 8
Out of these numbers marked on spinner number of vowels are = 3
Therefore the sample set n(S) is = 8
and the favorable events are n(E) = 3.
As per rules of the probability, the probability of spinning the spinner and landing on vowel will be = \frac{n(E)}{n(S)}=\frac{3}{8}
Now probability of spinning the spinner and not landing on a vowel will be
P(E)' = 1-\frac{3}{8}=\frac{5}{8}
Option C. \frac{5}{8} is the answer.
Answer:
x = ± 3
Step-by-step explanation:
Given
5x² - 45 = 0 ( divide through by 5 )
x² - 9 = 0 ( add 9 to both sides )
x² = 9 ( take the square root of both sides )
x = ± = ± 3
Thus the roots are x = - 3, x = 3
