Find the volume of the cone of with a height of 6cm and a diameter of the base or 6cm
Ainat [17]

Answer:

The volume of cone v= 113.04 cm³.

Step-by-step explanation:

Formula used to find volume of cone is:

v= \pi * r^2 * \frac{h}{3}

where r is the radius and h is the height of cone.

In the given question we are given:

height h= 6 cm

diameter d= 6 cm

We know radius r = d/2 = 6/2 = 3 cm

so, volume will be:

v= \pi * 6^2 * \frac{3}{3}

v= \pi * 36

v=113.04

So, the volume of cone v= 113.04 cm³ given height h= 6cm and radius r= 3cm

A set of data points has a line of best fit of y = –0.2x + 1.9. What is the residual for the point (5, 1)?
alisha [4.7K]
<span>A. 0.1
    The residual is the difference between the observed value and the predicted value for a data point. You obtain it by subtracting the predicted value from the observed value. So the predicted value is: y = -0.2x + 1.9 y = -0.2*5 + 1.9 y = -1 + 1.9 y = 0.9 Therefore the residual is: r = 1 - 0.9 r = 0.1 And the value of 0.1 matches option "A".</span>

A number d minus 2 is less than -1 ?
tamaranim1 [39]

d - 2 < -1 is how this inequality would be displayed.

However, we can solve for the value of d by treating this like a standard algebraic equation.

d - 2 < -1

<em><u>Add 2 to both sides.</u></em>

d < 1

The value of d is less than 1.

Let me know if you have any other questions.
