Answer:

A. 1/4 as large

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

Cut the radius in 1/2

V = pi (1/2r)^2 h

V = pi (1/4) r^2 h

V = 1/4 pi r^2 h

The volume is 1/4 what is was before we cut the radius in 1/2

The sum of three consecutive even numbers is 114 what's the smallest of these numbers

laila [671]

Answer:

Step-by-step explanation:

consecutive even numbers are 2,4, 6...

Let the smallest of the 3 numbers be x.

2nd number= x+2

3rd number

=x+2+2

= x+4

sum of the 3 numbers= x +x+2 +x+4

114= 3x+6

3x= 114 -6 (-3 on both sides)

3x= 108 (simplify)

x= 108 ÷3

x= 36

Thus, the smallest number is 36.

Let's check!

36+38+40= 114 ✓
