A cone has a diameter of 18 units and height of 8 units. What is its volume?

m_a_m_a [10]

Answer:72

Step-by-step explanation:Given : A cone has a diameter of 18 units and height of 8 units.

We have to determine the volume of the given cone.

We know Volume of cone = 1/3 $\pi \\$ $r^{2}$ $h$

Where r is radius of cone

h is the height of cone

Given : diameter = 18units so, radius is half of diameter = 9 units

height = 8 units

Substitute, we have,

Volume of cone = 1/3 $n\\$ $(9^{2} ) 8$

Simplify, we have,

Volume of cone = $72\pi$

Thus, the volume of given cone is 72π cubic units.

Find the distance of PQ<br> P(0,4) and Q(10,-6)

solong [7]

Answer:

PQ ≈ 14.14 units

Step-by-step explanation:

calculate the distance d using the distance formula

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

with (x₁, y₁ ) = P (0, 4 ) and (x₂, y₂ ) = Q (10, - 6 )

PQ = $\sqrt{(10-0)^2+(-6-4)^2}$

= $\sqrt{10^2+(-10)^2}$

= $\sqrt{100+100}$

= $\sqrt{200}$

≈ 14.14 units ( to 2 dec. places )
