The formula for the circumference of a circle is
  C = 2π·r
or
  r = C/(2π)
The radius r of cylinder A is
  r = (4π)/(2π) = 2

The formula for the area of a circle is
  A = π·r²
or
  r = √(A/π)
The radius of cylinder B is
  r = √(9π/π) = 3

The dimensions of cylinder A must be multiplied by 3/2 to produce the corresponding dimensions of cylinder B.

A has a radius of 2 (4pi/pi = 4 diameter, 4/2 = 2 radius)
B has a radius of 3 (9pi/pi = 9, 9 is r squared, so the sqrt of 9 is 3)
A * x = B
2 * x = 3
x = 3/2
The answer is C), 3/2

6. Regroup the numbers in the following problems, putting the numbers that add up to 10 or a multiple of 10 in parentheses.
svetoff [14.1K]

Answer:

a) (2+8)+9

b) (3+7)+5+4

c) (4+16)+2

d) (31+9)+4

Step-by-step explanation:

a) 2+9+8

2 and 8 add up to 10, so we regroup them in parentheses

(2+8)+9


b) 3 + 5 + 4 + 7

3 and 7 add up to 10, so we regroup them in parentheses

(3+7)+5+4


c) 4 + 2 + 16

4 and 16 add up to 20 which is a multiple of 10, so we regroup them in parentheses

(4+16)+2


d) 31 + 4 + 9

31 and 9 add up to 40 which is a multiple of 10, so we regroup them in parentheses

(31+9)+4
