A circular sector is the area between two radii of a circle and the arc between them.
The area is indeed given by
pi*r^2*(arc angle/360)
=pi*10.5^2(118/360)
=36.1375 pi cm^2
=113.529... cm^2
Therefore your answer is correct, to the first decimal place.
Perhaps you can check if the question specifies a different accuracy for the answer, or a different value of pi to be used.
2. Area of the entire figure = 14f + 20 units².
Perimeter of the entire figure = 6f + 18 units².
3. D. 8.
4. 11/15
<h3>How to Find the Perimeter and Area of a Rectangle?</h3>
Perimeter = 2(length + width)
Area = (length)(width).
2. Decompose the shape into two rectangles, rectangle 1 and rectangle 2.
Length of rectangle 1 = f
Width of rectangle 1 = 4
Area of rectangle 1 = (f)(4) = 4f units²
Length of rectangle 2 = 2f + 4
Width of rectangle 2 = 5
Area of rectangle 2 = (2f + 4)(5) = 10f + 20 units²
Area of the entire figure = 4f + 10f + 20
Area of the entire figure = 14f + 20 units².
Perimeter of the entire figure = 2f + 4 + 5 + f + 4 + f + 2f + 5
Add like terms
Perimeter of the entire figure = 6f + 18 units².
3. A factor of 44 is any number that can divide 44 without a remainder. 8 is not a factor of 44 because it cannot divide 44 without a remainder. So, the answer is: D. 8.
4. 33/45 = (3 × 11) / (3 × 15)
= 11/15

Answer:
21, 6, 12
Step-by-step explanation:
your welcome:)
Answer:
Writing the information in the form of ratio
Three point basket = Three point tries
3 : 4
27 : x
Think about multiplication , how many 3s do you need to make 27 ?
Its 27 ÷ 3= 9
Because you need 9 lots of 3, Then to make it proportional , you'd need 9 lots of 4
9×4 = 36
Three points tries is 36
perimeter should be 43 and the area should be 72m^2
this is squared btw
