Answer:
14 cm.
Step-by-step explanation:
Let the radius of the circle = r cm.
Then circumference of circle = 2 π r.
Since circumference exceeds the radius by 74 cm
Therefore, according to the question,
- Hence, the radius of the circle is 14 cm.

Answer:
<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>32</u></em></h2>
Step-by-step explanation:
4x - 7 - 3x + 4 =25
=> 4x - 3x = 25 + 7
=> <em><u>x = 32 (Ans)</u></em>
diagonal = sqrt(l^ + w^2)
17 = sqrt(10^2 + x^2)
17^2 = 10^2 + x^2
289 = 100 + x^2
189 = x^2
x = sqrt(189) = 13.747
X = 13.75
width is 13.75 inches
Answer:
let's devide the left equation by -1/2 to get it into a form that starts with y=...
y=-x-10
the right equation is
y=2x+2
since y=y the following must also be true (for the point where the two lines intersect):
-x-10=2x+2
add 1x on each side
-10=3x+2
subtract 2 on each side
-12=3x
devide by 3
-4=x
that's the x-information of the point. to get the y-information we plug it into one of the two function, any is fine actually, because the point we are looking for is on both of them after all.
I plug x = -4 into the second equation and get
y = 2*(-4) +2
y = -6
the two lines intersect at (-4,-6)
