Distributive property is the answer
The correct answer is B) 9 m.
The measure of the sector of circle R is 32π/9 m. The measure of the central angle is 80°. This means that the sector is 80/360 = 2/9 of the circle. The area of a circle is given by A=πr², so the area of the sector is A=2/9πr². To verify this, 2/9π(4²) = 2/9π(16) = 32π/9.
Using this same formula for circle S, we will work backward to find the radius:
18π = 2/9πr²
Multiply both sides by 9:
18*9π = 2πr²
162π = 2πr²
Divide both sides by 2π:
162π/2π = 2πr²/2π
81 = r²
Take the square root of both sides:
√81 = √r²
9 = r
Answer: 7,5
Step-by-step explanation:
Answer:
3 is yes, the rest is no
Step-by-step explanation:
for y = -6x - 9
(1) if x = 7, y = -51 => No
(2) if x = 3, y = -27 => No
(3) if x = -8, y = 39 => Yes
(4) if x = -5, y = 21 => No
The answer is 5/6 because 1/2 a chance to get a blue and 1/3 green so you add that together to get 5/6.
