Help<br> Find the volume of this cone.<br> Use 3 for TT.
natima [27]

Answer:

180ft^{3}

Step-by-step explanation:

Volume of a cone:

V=\pi r^{2} \frac{h}{3}

Take \pi as 3, as mentioned in the question

'r' is 'radius' ⇒ {diameter is given so divide by 2: 12/2 = 6}

'h' is 'height'

V=(3)(6)^{2} (\frac{5}{3} )

V=(3)(36)(\frac{5}{3} )

V=108(\frac{5}{3} )

{multiply 108 with 5 and then divide the answer by 3}

V=108 × 5

V=540

V=540/3

V=180ft^{3}

What is the distance between the points (-4, 2) and (1, -3) on the coordinate plane?
ruslelena [56]

Answer:

A. 7.07 units

Step-by-step explanation:

Use the distance formula for coordinates:

d=\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2   }

Fill in the coordinates accordingly:

d=\sqrt{(1-(-4))^2+(-3-2)^2}

which simplifies down to

d=\sqrt{25+25}

which is of course

d=\sqrt{50}

Plug that into your calculator and you'll get the answer
