Answer:
34cm3
Step-by-step explanation:
Volume of sphere = 4/3 pi x cube of radius
Radius =2cm , pi = 3.142
Volume = 4/3 x 3.142 x 2 x 2 x 2
Volume = 1.3333 x 3.142 x 8
Volume = 33.5cm3
Volume = 34cm3 to the nearest whole number

Answer:
9
Step-by-step explanation:
6n = n² - 27
n² - 6n - 27 = 0
n² - 9n + 3n - 27 = 0
n(n - 9) + 3(n - 9) = 0
(n - 9)(n + 3) = 0
n = -3, 9
Answer:
1080°
Step-by-step explanation:
(n - 2) x 180
n = number of sides = 8
(8 - 2) × 180 = 1080°
I’d say answer B would be the best bet
Answer:
y=2x+8
Step-by-step explanation:
You set the slope to the opposite of -1/2 which is 2/1 or 2.
Then you do b=2(4) (because 4 is the x in the coordinate points)
and solve for b you get 8 so
Y=2x+8
