Area of a sphere = 4(pi)(r)^2
Reverse the equation to find the radius (r)
The answer will be in pi form
32/81(pi)
8/20.25(pi)
Square root of 8/20.25(pi) = radius
r = 2.8(rounded)/4.5(pi)

Answer:
C. x=2
Step-by-step explanation:
-3(x-4)=2x+4-x
-3x+12=x+4
+3x +3x
-----------------------
12=4x+4
-4 -4
-----------------------
8=4x
-- ---
4 4
-----------------------
x=2
Solution: Z= -9
Reasoning: -6 - 3 = -9
Answer:
cross multiply
(8m)(11)=(6)(3)
88m=18
then divide by 88 on both sides
m=18/88 then reduce by 2 -----> 9/44

Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given
y = x² - 6x + 3
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² - 6x
y = x² + 2(- 3)x + 9 - 9 + 3
= (x - 3)² - 6 ← in vertex form
• If a > 0 then vertex is a minimum
• If a < 0 then vertex is a maximum
Here a = 1 > 0, thus
(3, - 6 ) is a minimum
