Answer:
-1/3 sqrt(21)
Step-by-step explanation:
1/3 sqrt(21) - 2/3 sqrt(3) * sqrt(7)
We know sqrt(a) * sqrt(b) = sqrt(ab)
1/3 sqrt(21) - 2/3 sqrt(21)
Factor out sqrt(21)
sqrt(21) (1/3-2/3)
sqrt(21) (-1/3)
-1/3 sqrt(21)
The answer is 192 because the middle part is equal to 168 then you add 12 two time for the two side in the right and left so it equals to 192
The answer is Between B and D. Did you do the math
Answer:
approximently symetic
Step-by-step explanation:
Area of a semicircle = 1/2 πr²
----------------------------------------------------
Find Radius:
----------------------------------------------------
1/2πr² = 76.97
r² = 76.97 ÷ 1/2π
r³ = 49
r = √49
r = 7
----------------------------------------------------
Find Diameter:
----------------------------------------------------
Diameter = Radius x 2
Diameter = 7 x 2
Diameter = 14 yards
----------------------------------------------------
Answer: 14 yards
----------------------------------------------------
