Answer:
623.61 cm³
Step-by-step explanation:
Given:
Radius of sphere (r) = 5.3 cm
Required:
Closest volume of the ball
SOLUTION:
Volume of a sphere = ⁴/3πr³
Radius (r) = 5.3 cm
Plug in the value of r
Volume = ⁴/3*π*5.3³
Volume = ⁴/3*π*148.877
Volume = 623.61 cm³
623.61 cm³ is closest to the volume of the ball.
Best represents 55? None of these points are 55. The closest answer I can get you is point D on 11 because 55 is divisible by 11...(5)
The equation is 50+10x-10 which would simply to 40+10x and then change the x to 5 ( now it’s 5 times 10 ) changing 10x to 50 . 50+40 equals 90 . GOOD LUCK
Answer:
D 12,000
Step-by-step explanation:
There is 1000 meters in every km
Step-by-step explanation:
To complete the square, take half of the second coefficient, square it, then add the result to both sides.
(-8/2)² = (-4)² = 16
x² − 8x + 16 = 9 + 16
Solving:
(x − 4)² = 25
x − 4 = ±5
x = 4 ± 5
x = -1 or 9
