Radius of the hollow centre of ball = 4 in
Volume = 4/3 πr³ = 4/3 * 3.14* 4³ = 267.95 in³
Volume of hollow centre is 267.95 in³
Hope it helps!
Answer:
x = 5 and y= 15
Step-by-step explanation:
3x + 2y = 45
4x - y = 5 (multiple both sides by 2)
or
3x + 2y = 45
8x - 2y = 10
--------------------( add side with side)
11x + 0 = 55
or x= 55/11 = 5
replace x =5 into 4x - y = 5 we have 4*5 - y = 5
20 - y = 5 or y = 20- 5= 15
So x = 5 and y= 15
Have a good day
Answer:
4x = y
Step-by-step explanation:
If y is 36 and x is 9, you know 9 x 4 = 36. So it would be 4x = y
