Answer:
The length of the circular arc is 8.64 inches
Step-by-step explanation:
Length of circular arc (L) = central angle/360° × 2πr
central angle = pie/4 = 45°, r (radius) = 11 inches
L = 45°/360° × 2 × 3.142 × 11 = 8.64 inches (to two decimal places)
Answer:
She needs at least 11 pieces of accessories.
Step-by-step explanation:
She needs $200 and she has $45
200 - 45 = 155
Now she needs $155 worth of accessories and each piece is worth $15
155/15 = 10.33
then you round up to find the answer of 11 pieces of accessories.
Answer:
AOB = 40 degrees
Step-by-step explanation:
The two smaller angles, AOB and BOC, add up to form AOC. That means that the angles of AOB and BOC sum up to the angle of AOC

3 1/4= 13/4
13/4×12=39
3/4÷39=1/52
The answer I 1/52
Answer:
D. 102.6 in²
Step-by-step explanation:
The area of the square is 9 in² (3 × 3 = 9)
The area of the rectangle is 30 in² (3 × 10 = 30)
The area of the circle is 63.585 (a = πr², a = 3.14 × 4.5² - remember that the radius of a circle is half of the diameter)
Now, we can add these numbers together. 9 + 30 + 63.585 is 102.585 in² which is 102.6 in² rounded to 1 decimal place.
Hope this helps!
