The answer is 24.5 because 19-13 \frac{1}{2} = 5 \frac{1}{2} so you add 5.5 from 19 to get the answer

Whats the Diameter? I really need help understanding this
Arada [10]

Answer:

1.8 in.

Step-by-step explanation:

Hi there!

<u>1) Determine the radius of the base</u>

V=\frac{1}{3} \pi r^2h where r is the radius of the base and h is the height of the cone

Plug in the known values (h=4.2, V=3.6)

3.6=\frac{1}{3} \pi r^2(4.2)

Isolate r; divide both sides by 4.2

\frac{3.6}{4.2} =\frac{1}{3} \pi r^2\\\frac{6}{7} =\frac{1}{3} \pi r^2

Multiply both sides by 3

\frac{6}{7}*3 =\pi r^2\\\frac{18}{7}=\pi r^2

Divide both sides by π

\frac{18}{7\pi }=r^2

Take the square root of both sides

\sqrt{\frac{18}{7\pi }} =r

<u>2) Determine the diameter</u>

Now that we have the radius, to find the diameter, multiply r by 2:

d=\sqrt{\frac{18}{7\pi }}*2\\d=1.8

Therefore, the diameter is 1.8 in. when rounded to the nearest tenth.

I hope this helps!

Bogdan [553]

Answer:

∠STR = ∠XYT


Step-by-step explanation:

The triangles are give congruent.△RST ≅ △TXY.

In congruent triangles corresponding angles are equal.The order of the letters in the congruent statement matters.

In the given statement the angles matching to ∠STR is ∠XYT.

Hence ,the equal angles in the congruent triangles are ∠STR = ∠XYT.

Eventually, the same system was adopted by the majority of people.
