The height of a cylinder is equal to the diameter of the base What expression represents the volume of the cylinder, in cubic un

Sveta_85 [38]

Answer: 3 units

Step-by-step explanation:

the volume of a cone C = πr²h/3

C = 18π, h =2x, r = diameter/2 = 2x/2 =x

18π = π* x²* 2x/3

divide through by π

18 = x² * 2x/3

multiply through by 3

54 = 2x³

divide through by 2

27 = x³

x =∛27 = 3

x = 3 units = radius

Can someone help me out with this please? I suck at fractions

xxMikexx [17]

164 inches x $\frac{1 foot}{12 inches}$ = $\frac{41}{3}$ ft

147 inches x $\frac{1 foot}{12 inches}$ = $\frac{49}{4}$ ft

2 $\frac{1}{4}$ ft = $\frac{9}{4}$

Perimeter = 2L + 2w - 1doorway

= 2 $(\frac{41}{3})$ + 2( $(\frac{49}{4})$ - $\frac{9}{4}$

= $\frac{82}{3}$ + $\frac{98}{4}$ - $\frac{9}{4}$

= $\frac{82}{3}$ + $\frac{89}{4}$

= $(\frac{4}{4} )$ $\frac{82}{3}$ + $(\frac{3}{3} )$ $\frac{89}{4}$

= $\frac{328}{12}$ + $\frac{267}{12}$

= $\frac{595}{12}$

= 49 $\frac{7}{12}$ ft

******************************************************************************

b) 49 $\frac{7}{12}$ ft ÷ 8ft = 6.2

A group of preschoolers has 30 boys and 13 girls what is the ratio of boys to all children?

vekshin1

A group of preschoolers has 30 boys and 13 girls then the ratio of boys to all children would be 30:43.

What is a ratio?

A ratio in mathematics shows how many times one number contains another. For example, if a bowl of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon-to-orange ratio is 6:8, and the orange-to-total fruit ratio is 8:14.

A group of preschoolers has 30 boys and 13 girls.

Total children will be = 30 + 13 = 43

Ratio = number of boys/total children

= 30/43.

Hence, if A group of preschoolers has 30 boys and 13 girls then the ratio of boys to all children would be 30:43.
