Answer:

  • 21 units
  • 9702 units³

Step-by-step explanation:

The area of the base is given by the formula ...

  A = πr²

so the radius is ...

  r = √(A/π) = √(1386/(22/7)) = √441 = 21 . . . units

__

The volume is given by ...

  V = (1/3)Bh

where B is the area of the base, and h is the height (equal to the radius). Filling in the numbers, we have ...

  V = (1/3)(1386)(21) = 9702 . . . . cubic units

Answer:

1. >; 2. >  

Step-by-step explanation:

1.

     ⅜ (?) 0.295    Convert ⅜ to a decimal fraction

0.375 (?) 0.295

We can use a <em>number line</em> to decide which number is greater.

In Fig. 1 below, when we go from 0.295 to 0.375, we are moving to the <em>RIGHT</em>,  so 0.375 is greater than 0.295.

0.375 >  0.295

2.

-0.770 (?) -4/5    Convert ⅘ to a decimal fraction

-0.770 (?) -0.800

In Fig. 2 below, when we go from -0.80 to -0.77, we are moving to the <em>RIGHT</em>,  so -0.770 is greater than -0.800.

-0.770 > -0.800

Answer it pls and explain too​
snow_tiger [21]

Answer:

  y-intercept: (0, 5); slope: 1/4

Step-by-step explanation:

The slope (m) is found from ...

  m = (y2 -y1)/(x2 -x1)

Using the first two points in the table, this is ...

  m = (8 -6)/(12 -4) = 2/8 = 1/4 . . . . . eliminates choices A and C

__

Then, the point-slope form of the equation of the line can be written as ...

  y -y1 = m(x -x1)

  y -6 = (1/4)(x -4) . . . fill in known values

  y = 1/4x -1 +6 . . . . . add 6

  y = 1/4x +5

Then the value of y when x=0 is ...

  y = 0 +5 = 5

So, the y-intercept is (0, 5) and the slope is 1/4, matching the last choice.
