snow_tiger [21]

Answer:

40

Step-by-step explanation:

In the triangle, there is a 90 degree angle and Angle 1 (what we are looking for) and the other angle, lets call is Angle 2.

Lets find Angle 2 first.

First of all, the angle between angle 40 and 90 can be found easily.

That angle (lets call it "x) and 40 and 90 make a straight angle (180 degrees). So we can write:

40 + x + 90 = 180

Lets solve for "x":

40 + x + 90 = 180

130 + x = 180

x = 180 - 130

x = 50

Now, This angle (50) and Angle 2 are same [vertical angles]

So,

Angle 2 = 50

Now, there are 180 degrees in 3 angles in a triangle. So for the triangle shown, we cacn write:

90 + Angle 1 + Angle 2 = 180

90 + Angle 1 + 50 = 180

Angle 1 + 140 = 180

Angle 1 = 180 - 140

<u>Angle 1 = 40</u>

A scoop of ice cream has 1.5 inch radius. How talk should the cream cone of the same radius be in order to contain all of the ic
MAVERICK [17]

Answer:

The cream cone should be <u>6 inches</u>.

Step-by-step explanation:

Given:

A scoop of ice cream has 1.5 inch radius.

Now, to find the height of the cream cone.

So, we need to get the volume of scoop by putting formula:

Radius (r) = 1.5 inch.

Using the value π = 3.14.

Volume=\frac{4}{3} \pi r^3

Volume=\frac{4}{3}\times 3.14\times 1.5^3\\\\Volume=\frac{4}{3}\times 3.14\times 3.375\\\\Volume=14.13\ inches^3.

<em>Thus, the volume of the ice cream scoop is 14.13 cubic inches.</em>

<em>So, to put all of the ice cream inside the cone.</em>

<em>We take the cream cone volume as the scoop volume.</em>

Let the height of cone be h.

<em>As, given radius is same.</em>

Now, to get the height of the cream cone we put formula of volume:

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

14.13=3.14 \times (1.5)^2\times \frac{h}{3}\\\\14.13=3.14\times 2.25\times \frac{h}{3}

<em>Multiplying both sides by 3 we get:</em>

<em />42.39=3.14\times 2.25\times h\\\\42.39=7.065\times h<em />

<em>Dividing both sides by 7.065 we get:</em>

6=h

h=6\ inches.

<u><em>Hence, the height of the cone = 6 inches.</em></u>

Therefore, the cream cone should be 6 inches.
