Answer:166.7 milliliters

Step-by-step explanation:

height(h)=13cm

Radius(r)=diameter ➗ 2

r=7 ➗ 2

r=3.5cm

π=3.14

Volume=(π x r^2 x h) ➗ 3

Volume=(3.14 x (3.5)^2 x 13) ➗ 3

Volume=(3.14x3.5x3.5x13) ➗ 3

Volume=500.045 ➗ 3

Volume=166.7cm^3

1 cm^3=1mL

Therefore 166.7cm^3=166.7mL

On his road trip, leon stops to refuel and get some snacks. he has the following purchases: 12 gallons of gas at $2.89 per gallo

olga_2 [115]

The price of all gallons 12*(2.89)=$34.68
a) the price of the granola bars 2*(1.59)=$3.18
b) 1 apple=$0.89
c) 2 bottles of vitamin 2*(1.39)=$2.78

a)+b)+c)=6.85$, the 7.5% of this amount is $0.51

so finally, Leon should have paid $6.85+ $0.51+ $34.68 =$42.04

but he paid $44.64, so the true answer is C) he paid $2.60 too much ($44.64 - $42.04 =$2.60)

Triangle MNO is an equilateral triangle with sides measuring 16 StartRoot 3 EndRoot units. Triangle M N O is an equilateral tria

Lesechka [4]

Answer:

The correct option is second one i.e 24 units.

Therefore the height of the triangle is

$NR=24\ units$

Step-by-step explanation:

Given:

An equilateral triangle has all sides equal.

ΔMNO is an Equilateral Triangle with sides measuring,

$NM = MO = ON =16\sqrt{3}$

NR is perpendicular bisector to MO such that

$MR=RO=\dfrac{MO}{2}=\dfrac{16\sqrt{3}}{2}=8\sqrt{3}$ .NR ⊥ Bisector.

To Find:

Height of the triangle = NR = ?

Solution :

Now we have a right angled triangle NRM at ∠R =90°,

So by applying Pythagoras theorem we get

$(\textrm{Hypotenuse})^{2} = (\textrm{Shorter leg})^{2}+(\textrm{Longer leg})^{2}$

Substituting the values we get

$(MN)^{2} = (MR)^{2}+(NR)^{2}\\\\(16\sqrt{3})^{2}=(8\sqrt{3})^{2}+(NR)^{2}\\\\(NR)^{2}=768-192=576\\Square\ rooting\ we\ get\\NR=\sqrt{576}=24\ units$
