You could draw a parallelogram.
Answer:
radius: 3 units <----> Circumference: 18.84 units
Diameter: 12 units <----> Circumference: 37.68 units
Diameter: 36 units <----> Circumference: 113.04 units
Radios: 5 unites <----> Circumference: 31.4 units
Step-by-step explanation:
How I got the answers for the radiuses:
3 (this is only half the diameter so if you do 3 x 2 you will get the diameter.)
3 x 2 = 6
C = pi x d
C = 3.14 x 6
C = 18.84 [this is the first radios]
5 (this is only half the diameter so if you do 5 x 2 you will get the diameter.)
5 x 2 = 10
C = pi x d
C = 3.14 x 10
C = 31.4 [this is the second radios]
How I got the diameters:
12 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 12
C = 37.68 [this is the first Diameter]
36 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 36
C = 113.04 [this is the second Diameter]
Area = 1/2 x base x height
Let the height be x.
Height = x
Base = 2x
Area of triangle = 1/2 x base x heght
Plug base and height into the variables:
(1/2)(2x)(x) = 196
Combine like terms:
x² = 196
Square root both sides:
x = 14
Find Base and height:
Base = x = 14 km
Height = 2x = 2(14) = 28 km
Answer: Height = 28km
Answer:

Step-by-step explanation:
Work to isolate x on one side of the inequality:

Therefore the answer is all x values larger than or equal to -30
