Answer:

x =20

Step-by-step explanation:

As a line is 180 degrees

So 7x + 40 would be 180, which would lead us with the equation:

7x+40=180

=7x =140 (minus both sides by 40)

=x =20 (divide both sides by 7)

Use the following net to find the surface area of the solid figure it represents.

hodyreva [135]

Answer:

The solid formed is a cylinder

The total surface area is $131.88cm^2$

Step-by-step explanation:

The given net is made up of a rectangle and two circles.

The total surface area is the area of the rectangle plus the area of the two circles.

This implies that:

$S.A=75.36+2(28.26)$

$\implies S.A=75.36+56.52$

$\implies S.A=131.88cm^2$

The rectangular surface can be folded into the curved surface of a cylinder with the two circles becoming the lid.
