The two heaviest pumpkins weigh 19.5 lbs. Together, they weigh 35 lbs.

The two lightest pumpkins weigh 10 lbs and 10.75 lbs. Together, they weigh 20.75 lbs.

35 - 20.75 = 14.25 lbs

Hope this helps!

The circumference of a circle is 28π inches. What is the length of the radius of this circle?

devlian [24]

Answer:

The radius of the circle is 14 inches.

Step-by-step explanation:

How is the circumference of a circle related to its radius?

$\displaystyle \text{Circumference} = \pi\times \text{Diameter} = \pi\;(2\times \text{Radius})$ .

In brief,

$\text{Circumference} = 2\pi\times \text{Radius}$ .

For this question,

$\text{Circumference} = 28\pi$ , and
$\text{Radius}$ needs to be found.

Divide both sides of the equation by $2\pi$ :

$\displaystyle \frac{\text{Circumference}}{2\pi} = \text{Radius}$ .

$\displaystyle \text{Radius} = \frac{\text{Circumference}}{2\pi} = \frac{28\pi}{2\pi} = 14$ .

In other words, the radius of this circle is 14 inches.

Answer: The triangles are similar. They are actually exactly the same.

Step-by-step explanation: (Statement) The reason I know these triangles are similar is because I flipped one up and realized they matched just opposite each other. Then I matched them up they were exactly the same

The surface are I cannot find

Ilia_Sergeevich [38]

check the picture below.

so the triangular prism is really just 3 rectangles and 2 right-triangles,

now, we know the base of one of the triangles is 2.6, what's its height?

since it's a right-triangle, we can simply use the pythagorean theorem to get "h".

$\bf \textit{using the pythagorean theorem}
\\\\
c^2=a^2+b^2\implies \sqrt{c^2-a^2}=b
\qquad
\begin{cases}
c=\stackrel{hypotenuse}{5.2}\\
a=\stackrel{adjacent}{2.6}\\
b=\stackrel{opposite}{h}\\
\end{cases}
\\\\\\
\sqrt{5.2^2-2.6^2}=h\implies 4.5\approx h$

so, we can now, simply get the area of both of the triangles and the three rectangles and sum them up, and that's the area of the triangular prism.

$\bf \stackrel{two~triangles}{2\left[ \cfrac{1}{2}(2.6)(4.5) \right]}~~+~~\stackrel{rectangle}{(2.6\cdot 4.3)}~~+~~\stackrel{rectangle}{(4.3\cdot 3.9)}~~+~~\stackrel{rectangle}{(4.3\cdot 5.2)}
\\\\\\
11.7+11.18+22.36\implies \blacktriangleright 45.24 \blacktriangleleft$
