Answer:
Step-by-step explanation:
C = 2 π r
A = π r²
~~~~~~~~~~~
(1). C = 8 π
Let the length of the arc ADB is "x"
x = ( 8π ÷ 360° ) × 340°
x = 
(2). A = 16 π
The area of shaded region is
( 16 π ÷ 360° ) × 340° = 
Answer:
the length is 4
Step-by-step explanation:
we know the area is 12 4x3=12 so either 4 or 3 is the length the word problem says the width is one less than the lengh therefore the answer is 4 your welcome
Use the permutation formula
nPr = (n!)/((n-r)!)
20P15 = (20!)/((20-15)!)
20P15 = (20!)/(5!)
The final answer is choice A
Answer:
1 3/4
Step-by-step explanation:
2/8 * 7
2/8 will simplify
Divide the top and bottom by 2
12/8 = 1/4
1/4*7
7/4
We need to change this from an improper fraction to a mixed number
4 goes into 7 once with 3 left over
1 3/4
Answer:
Area = 53 in²
Step-by-step explanation:
area of a box = 8 * 6 = 48 in²
area of a triangle = 1/2 * b * h
b = 6 - 4 = 2 in
h = 13 - 8 = 5 in
area of a triangle = 1/2 * 2 * 5 = 5 in²
total area = area of a triangle + area of a box
total area = 5 in² + 48 in²
total area = 53 in²
