The answer for the following part is

<h3>What is Volume?</h3>

Surface area is the amount of space covering the outside of a three-dimensional shape.

Surface Area of Cone,

= πrl + πr²

=3.14*8*15.77 + 3.14* 8*8

= 597.61804 mm²

Surface Area of triangular pyramid,

= apothem * slant height * length

= 73.6 m²

Surface Area pentagonal pyramid

= B + LA

= 247.75 + 5 ( 1/2*12*19.5)

= 247.75 + 5 ( 117)

= 832.75 in²

Surface area of square pyramid

= P*l /2

= 2400 ft²

PLEASE HELP! BRAINLIEST! What is the value of x?

IceJOKER [234]

Solution here,

In the figure, the upper small triangle is similar to a lagre triangle.

Now, from the property of similar triangle,

$\frac{5}{40 + 5} = \frac{3}{3 + 2x + 10} \\ or \: \frac{5}{45} = \frac{3}{13 + 2x} \\ or \: 13 + 2x = 27 \\ or \: 2x = 27-13 \\ or \: x = \frac{14}{2} \\ or \: x = 7$

therefore, x= 7
