What is the answer to this in cm
jasenka [17]
The hardest part is finding the length of the curve at the top. To find arc length, multiply the circumference by the arc angle divided by full angle (360°) in a circle. Or:
s = (2\pi  r)( \frac{x}{360})
x, the arc angle in a semicircle, is 180°.
r, the radius is 7/2 = 3.5.
Now just plug the numbers in and solve for arc length, s.

s = 2π(3.5)(1/2) ≈ 11.00

Now just add up all the sides. 11cm + 10cm + 10cm + 7cm = 38 cm.

Emily spent a total of $38.04 on four CDs in a CD cost the same amount what is a reasonable amount for the cost of each city exp
pashok25 [27]
In order to find the cost of each CD, you would have to divide $38.04 by 4 CDs and you would get $9.51 as the cost of each CD. If you want to check if your answer is correct, you can either add $9.51 four times to get $38.04 or you can multiply $9.51 x 4 and you should get $38.04 remember that multiplication is always a way to check your answer for division problems and division is always a way to check an answer to your multiplicatiom problems. Just search it up for more info. Hope i helped! :)
