Answer:
The area of an octagon whose perimeter is 120 cm is 1086.4 
Step-by-step explanation:
An octagon is a polygon with eight sides. If the lengths of all the sides and the measurement of all the angles are equal, the octagon is called a regular octagon.
There is a predefined set of formulas for the calculation of perimeter, and area of a regular octagon.
The perimeter of an Octagon is given by
and the area of an Octagon is given by
We know that the perimeter is 120 cm, solving for side length (a) in the perimeter formula we get
Now, we calculate the area
Answer:
CAN'T TELL . BECAUSE I HAVEN'T SEEN SUCH A QUESTION BEFORE
Answer:
98 square centimeters
Step-by-step explanation:
first find the area of the non shaded area
8x4=32
next find the area of the rectangle around it
13x10=130
and last you need to subtract the non shaded area from the rectangle around it to find the area of the shaded area
130-32=98
Answer:
f (-4) = 3x(-4)^2 - 7x(-4) - 32 = 44
Step-by-step explanation:
you should replace every x with the number given which is here equals -4
Using the law of sins:
X/ sin(44) = 4510/sin(180-44-36)
x / sin(44) = 4510 / sin(100)
x = 3,181 yards.
