Rectangle = 8x16 = 128
Triangle = (1/2)(3)(6) = 9
Area of the irregular shape = 128 + 9 137 sq ft
Answer:
x + 4 = 10
Step-by-step explanation:
a number: x
a number increased by 4: x + 4
a number increased by 4 is 10: x + 4 = 10
Since 4 + x and x + 4 are the same, you are correct.
The only irrational number there is C
The diameter of circle B is 50 cm.
Step-by-step explanation:
Given,
The circumference of circle A = 314.159 ft
Diameter of Circle B is half of the diameter of circle A.
Let, the radius of circle A is r
To find the diameter of circle B
Formula
Circumference of a circle of radius r = 2πr
According to the problem,
2πr = 314.159
or, r = 
= 50 (approx)
So,
The diameter of circle A = 2×50 cm = 100 cm
The diameter of circle B = 50 cm.
