Answer:
r = 24 ft
Step-by-step explanation:
Circumference is given by
C = 2 * pi *r
We know that C = 48 pi
48 pi = 2 * pi * r
Divide each side by pi
48 pi /pi= 2 * pi * r/pi
48 = 2 r
Divide each side by 2
48/2 = 2r/2
24 = r
Answer:
25 in; C

Hey!
There probably is a reason she is deleting. You could contact her or ask some help elsewhere.
Anyway! I'm trying to get this in fast. (Remember the Pythagorean Theorem?) That will be very useful here since it is a right triangle.
<u>L² + L² = H² (or H² - L² = L²):</u>
In that case, we'll use the second one because our Hypotenuse is given.
We can substitute each value of the numbers:
65² - 60² = L²
Evaluating:
4225 - 3600 = 625
√625 = 25 inches
Thusly, the third side would be 
<em>Also note we could have simplified into a Pythagorean Triple. This method is a simpler more basic method for learning the concept.</em>
Hope this helps!
Answer:
34
Step-by-step explanation:
Marcy got 15% of the 40 wrong
.15 *40
6
If she got 6 wrong, then she got the rest right
40-6 = 34
She got 34 right
<span>We know Sin theta is given by Perpendicular/ hypotenuse.
Hence in this case the angle given is 30 degree and hypotenuse is given as 10 foot.
Hence Sin 30= P/ 10
1/2= P/10
Hence on solving value of P is 5.
Now we have to compute the theta value for Perpendicular as 5 and now the height of ramp is increased to 15 foot, hence hypotenuse is now 15 foot.
Hence Sin theta= 5/15
On taking inverse of Sin Theta we will get the theta value as 19.47.
Hence the angle of ramp should is 19.47 degrees.</span>
