Answer:

25.12

Step-by-step explanation:

the formula of a cone is pi r^2 * h/3

r = radius and h = height

the radius is 2 and the height is 3

and the question says use 3.14 instead of pi so

we have

3.14 * 2^2 * 6/3

2*2 or 2^2 = 4

3.14 * 4 * 6/3

6/3 = 2

3.14 * 4 * 2

4*2 = 8

and 8 * 3.14 is 25.12

In a lab, a substance was cooked by 42 C over a period of 7 hours at a constant rate. What was the change in temperature each ho
Mekhanik [1.2K]

Given that we have the change in temperature over 7 hours and we are looking for the change over 1 hour, we can divide the total change in temperature by 7. Thus, the change in temperature would be \frac{42}{7} C^{\circ}.


Additionally, this can be solved by equations:

\dfrac{42 \,\textrm{C}^{\circ}}{7 \,\textrm{hours}} = \dfrac{x \,\textrm{C}^{\circ}}{1 \,\textrm{hour}}

1 \,\textrm{hour} \cdot \dfrac{42 \,\textrm{C}^{\circ}}{7 \,\textrm{hours}} = x \,\textrm{C}^{\circ}

\dfrac{42}{7} \,\textrm{C}^{\circ} = x \,\textrm{C}^{\circ}

\dfrac{42}{7} = x


By using two different methods, we can determine that the change each hour was equal to 42/7 C° per hour.

Which graph shape represents the polar curve r = 1 + 4sin(θ)?
umka2103 [35]

Answer:

A cardioid

Step-by-step explanation:

A cardioid is a curve in the shape of a heart traced by a point on the circumference of a circle as it rolls around a fixed circle of the same radius.

The equation of vertical cardioid is r=a ± a\sin \theta

Given the polar curve is r= 1+ 4 \sin \theta

This is an equation of vertical cardioid.

So, it represents a cardioid.

Please help and add explanation:)
Anni [7]

Answer:

NO

Step-by-step explanation:

The above image shows two triangles. if we look at the top triangle, we notice it's two sides are equal (16 and 16). We therefore have an isosceles right triangle.

looking the second triangle, we notice that one side is 39, the other 40. Since these are the two sides joined at the point of intersection for the two images, and since 39 does not equal 40, the second triangle cannot be an isosceles right triangle. We conclude that the two triangles are not similar.
