The arc length by definition is given by:
S = r * theta
Where:
R: radius
Theta: central angle
For this case we have that the arc length is:
S = (30/180) * 9 * pi
S = (3/2) pi
Answer:
The length of the arc shown in red is:
S = (3/2) pi
For the middle square: 20in x 20in= 400in
For ONE flap: 20in x 12in= 240in
Multiply by 4 to get the area of all the flaps: 240in x 4 flaps= 960in^2
Add: 400+960= 1360in^2
Answer:
A) 18%
Step-by-step explanation:
Find percent change by subtracting to find the change, then put that over the original amount and times by 100.
79 - 65 is 14
change/original is
14/79
= .177
Then times 100 to make the decimal into a percent.
0.177×100 is 17.7%
which rounds to 18%.
