Answer:   B. 254.34 cm^2

Step-by-step explanation:

The area of a circle is pi times the radius squared.

Using the diameter we have to find the radius.

The diameter is two times the radius meaning that the radius is half the diameter.

18/ 2 = 9

The radius will be 9 cm

Now using the formula   v= pi * r^2    ,  input the value for pie and the radius and solve for  v  the volume

v = 3.14 * 9^2

v= 3.14 * 81

v = 254.34 cm^2

Answer:

The answer would be B) 254.34 cm2

Answer:

982.5

Step-by-step explanation:

Always do the parenthesis first

1/2 * 1, 341 + 1/2 * 625

670 + 312.5

982.5

Answer:

Step-by-step explanation:

by inspection.. ( looking at the graph)  we can see that the slope is down hill. so it's going to be negative and also  slope = rise / run     [rise is negative in this question] soo ... i'm looking carefully to see where the line is crossing the grid marks exactly .. it looks like to me  (-3,1) and (2,-3)   you tell me if that looks right... if it does .. then the rise / run is 4/5  and this is a negative slope  sooo  

- 4/5

Answer:

value of x = 8

Step-by-step explanation:

well here,

line x is parallel to the line measuring 18

so the two triangles are similar to each other

hence ratio of their sides are equal

so 6/ 12 = x/ 16

=》1/2 = x/16

=》 x = 16 / 2

=》 x = 8

i hope u got it

have a nice day

Answer:

x = [tex]\frac{16}{3}[/tex]

Step-by-step explanation:

The outer and inner triangles are similar, thus the ratios of corresponding sides are equal, that is

[tex]\frac{6}{6+12}[/tex] = [tex]\frac{x}{16}[/tex] , that is

[tex]\frac{6}{18}[/tex] = [tex]\frac{x}{16}[/tex] ( cross- multiply )

18x = 96 ( divide both sides by 18 )

x = [tex]\frac{96}{18}[/tex] = [tex]\frac{16}{3}[/tex]

Answer:

The difference between their volumes is [tex]237.375ft^3[/tex]

Step-by-step explanation:

The attachment completes the question.

For cube 1:

[tex]s_1 = 8ft[/tex]

For cube 2:

[tex]s_2 = 6.5ft[/tex]

Required

The difference in their volumes

First, we calculate the volume of box 1

[tex]V_1 = s_1^3[/tex]

Substitute 8 for s1

[tex]V_1 = 8^3[/tex]

[tex]V_1 = 512ft^3[/tex]

Next, we calculate the volume of box 2

[tex]V_2 = s_2^3[/tex]

Substitute 6.5 for s2

[tex]V_2 = 6.5^3[/tex]

[tex]V_2 = 274.625ft^3[/tex]

The difference is then calculated as:

[tex]Difference = |V_1- V_2|[/tex]

[tex]Difference = |274.625- 512|[/tex]

[tex]Difference = |-237.375|[/tex]

[tex]Difference = 237.375[/tex]

Hence, the difference between their volumes is [tex]237.375ft^3[/tex]

Answer:

$79.08

Step-by-step explanation:

Find 20% of 65.90. 20% as a decimal is 0.20. Multiply 0.2 and 65.90.

65.90 x 0.20 = 13.18

Add 13.18 to the original price.

13.18 + 65.90 = 79.08

Answer:

[tex]x = 5[/tex]

Step-by-step explanation:

[tex] {2}^{2x - 3} + 52 = 180[/tex]

[tex] {2}^{2x - 3 } = 128[/tex]

[tex] {2}^{2x - 3} = {2}^{7} [/tex]

[tex]2x - 3 = 7[/tex]

[tex]2x = 10[/tex]

[tex]x = 5[/tex]

Answer:

4m-8

Step-by-step explanation:

answer

Answer:

4m - 8

Step-by-step explanation:

Given expression,

→ m - (8 - 3m)

Simplifying the expression,

→ m - (8 - 3m)

→ m - 8 + 3m

→ 4m - 8

→ 4(m - 2)

Hence, answer is 4m - 8.

Answer:

y=89

Step-by-step explanation:

because if you take y-47 okay then you do 47+42 giving you what that ange is because they are the same angle they should both be 42

Step-by-step explanation:

-6x + 5 > -1

-6x > -6 (subtract 5 on both sides)

x < 1 (divide -6 on both sides, flip the sign)

Hence the answer is x < 1.

Answer:

  80

Step-by-step explanation:

Let m represent the number of males. Then you have ...

  m/(180 -m) = 4/5

  5m = 4(180 -m) . . . . cross multiply

  9m = 720 . . . . . . . . add 4m, simplify

  m = 80 . . . . . . . . . . divide by 9

The number of males at the fair was 80.
