Answer:
51.9 cm²
Step-by-step explanation:
From the diagram attached,
Area of the white region(segment)(A) = Area minor sector- area of the triangle
A = (πr²∅/360°)-(1/2r²sin∅)............... Equation 1
Where r = radius of the circle, Ф = reflex angle formed at the center of the circle, π = pie
From the question,
Given: r = 7 cm, Ф = 150°
Constant: π = 22/7
Substitute these values into equation 1
A = [(22/7)×7²×150/360]-[(1/2)×7²×sin150]
A = 64.17-12.25
A = 51.92
A = 51.9 cm²
Answer:
b is right
Step-by-step explanation:
There are 3feet in one yard.
Let B = number of feet
Let Y = number of yards
B = 3Y

Answer:

3/4x = -24
To isolate the "x" variable, divide both sides by 3/4 (multiply by its reciprocal, or 4/3)
3/4x · 4/3 = -24 · 4/3
x = (-24 · 4) / 3
x = -32.
