First, multiply by the reciprocal and continue.
Answer:
-2.25
Step-by-step explanation:
Answer:
14 pi or approximately 43.96
Step-by-step explanation:
To find the circumference of a circle, we can use the formula
C = 2*pi*r
C = 2*pi*7
C = 14 pi
We can approximate pi as 3.14
C = 14*3.14
C is approximately 43.96
Area = 1/2 base x height
Area = 1/2 (2 x height) x height
Area = height x height
Area = height^2
100 = height^2
height = SquareRoot(100)
Height = 10
Base = 2 x height = 2 x 10 = 20
Perimeter is distance all around the side of the figure, so you would do:
8 + 7 + 19 + 3 + y + x
Plug in y and x that you solved before: 8 + 7 + 19 + 3 + 11 + 4
Add them!: 52
The perimeter is 52 meters.
