If you have to find Lateral Superficial Area just do P (perimeter of base) * h

So (8+19+10+7) * 8 = 44*8 = 352 cm^2

If you have to find Total Superficial Area the formule is LA + 2[(B+b)*h/2]

TA = 352 + 2[(19*8)/2] = 352+2(76) = 352+152 = 504 cm^2

35 – 2.4 ( 7 – 5)<br> Show each step

saveliy_v [14]

Answer:

35 - 2.4(7-5)

= (35/1)-(24/10)(7-5)

= [(35×10)/(1×10)]-(24/10)(2)

= (350/10)-(24/10)(2)

= (350-24)/10(2)

= 326/10(2)

= 32.6(2)

= 65.2

Thank you.

A glider flies 13 miles north from the airport and then 24 miles diagonally southeast. Approximately how far west does the glide

NISA [10]

Answer:

20.2 miles

Step-by-step explanation:

This can be described by the three sides of a right angled triangle. Let the distance of the glider to the airport be represented by x, applying the Pythagoras theorem:

$/hyp/^{2}$ = $/adj1/^{2}$ + $/adj2/^{2}$

$/24/^{2}$ = $/x/^{2}$ + $/13/^{2}$

576 = $x^{2}$ + 169

$x^{2}$ = 576 - 169

= 407

x = $\sqrt{407}$

= 20.1742

x = 20.2 miles

The glider has to fly 20.2 miles to return to the airport.

What is the volume of this cone?

olchik [2.2K]

Answer:

The volume of the cone is approximately 453.0 cm³

Step-by-step explanation:

The volume of a cone is one third that of a cylinder with the same height and radius. That gives us 1/3 πr²h, where r is radius and h is height.

However, we are not given the height of the cone, but the side length. We can work out the height using the Pythagorean theorem, as we have a right triangle with the height, base radius, and length. You may recall that the Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of it's other two sides:

$a^2 = b^2 + c^2$

So we can find the height of the cone with that:

$10.8^2 = 7.4^2 + h^2\\h^2 = 10.8^2 - 7.4^2\\h^2 = 116.64 - 54.76\\h^2 = 61.88\\h = \sqrt{61.88}\\h \approx 7.9$

Now that we have the cone's height, we can solve for its volume:

$v = \frac{1}{3} \pi r^2 h\\v = \frac{1}{3} \pi \times 7.4^2 \times 7.9\\v = \frac{1}{3} \pi \times 54.76 \times 7.9\\v = \frac{1}{3} \pi \times 432.6\\v = \pi \times 144.2\\v \approx 453.0 cm^3$
