Answer:

Step-by-step explanation:

Do this using a guess and check, starting with 5.

5 x 5 = 25

25 - 60 wouldn't work

10 x 5 = 50

50 - 60 wouldn't work either

15 x 5 = 75

75 - 60 = 15

Your answer is 15.

Need to find the volume. measurements in picture, please help.

o-na [289]

Answer:

V = 288.5 $yd^{3}$

Step-by-step explanation:

To find the volume of a cone, use this equation:

$V = \pi r^{2}\frac{h}{3}$

r = radius

h = height

We aren't given the height of the cone, just the length of the side. To find the height use the Pythagorean Theorem:

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

The value of 12.1 yds is the hypotenuse and the radius is the value of one of the legs. So, set it up like this:

$a^{2}+5^{2} =12.1^{2}$

Now, solve:

$a^{2}+25= 146.41$ Distribute the square

$a^{2} = 121.41$ Subtract 25 from 146.41

$\sqrt{a^{2} }=\sqrt{121.41}$

a = 11.01862

So, the height is equal to 11.01862 yds.

Now, we can plug everything into the volume equation:

$V = \pi (5)^{2}\frac{11.01862}{3}$

Simplify (use calculator):

V = 288.5 $yd^{3}$

So, the volume of the cone is equal to 288.5 $yd^{3}$

Answer:

96 cm²

Step-by-step explanation:

The lateral surface area (A) is the sum of the areas of the 4 slant faces.

The faces are triangular with area $\frac{1}{2}$ bh , thus

A = 4 × $\frac{1}{2}$ × 8 × 6 = 2 × 48 = 96 cm²
