e-lub [12.9K]

<u>Answer </u>

Option A) 17cm

<u>Explanation </u>

Polygon R and polygon S are similar. This means the polygon R and S have equal number of sides.

Step 1 : Find the number of sides of polygon S

The perimeter of polygon S is 64 cm. If one side of polygon S is 8 cm

Therefore, Number of sides of polygon S = 64/8 = 8 sides

and number of sides of polygon R = 8 side

Step 2 : Find the number of sides of polygon R

The perimeter of polygon R is 136 cm,  

Number of sides of polygon R = 136/8 = 17 cm

Therefore side length of  polygon R = 17 cm

Zanzabum

Answer:

755.98 ft^2

Step-by-step explanation:

Height of the Cylinder= 30 feet

Diameter = 8 feet

Radius= Diameter/2 = 8/2 = 4 feet

The Amount of Metal Sheet used in constructing the tank is the Total  Surface Area of the Tank.

Total Surface Area of a Cylinder =

=2\pi r(r+h)\\=2*\pi*4(4+30)\\=8*\pi*30=\\=240\pi\\=755.98 ft^2
