I'm pretty sure it's -4x.
Answer:
B
Step-by-step explanation:
Cos is the adjacent side over the hypotenuse. The adjacent side to <E is side ED. The hypotenuse is side EF. ED/EF. They do not go right out and give you this choice, but you see that B says the same thing.
You need to figure the area of the large rectangle and then add the area of the half circle
rectangle
one long side is 18 in and width is 9
l x w is 162 Sq in
full circle is pi r squared
3.14 x 4.5^2
63.58
half circle would be 31.79
add 31.79 and 162
193.79 Sq ft
Answer:
hope it helps you see the attachment for further information...
The formula for finding the area of a circle is π r ²
the radius is half of the diameter therefore the radius is 4
so, 3.14 x 4² = 50.24
A= 50.24cm²
