Each length is 72 times longer so the actual dimensions are 381.6cm by 576 cm
Answer:
=150.79644...cm²
~150cm²
Step-by-step explanation:
cylinder surface area = 2 pi r h + 2 pi r²
Answer:
Add all the values up and then divide by 2
Step-by-step explanation:
Area of each side triangle is 1/2*8*15 = 60. There are 5 of them so the triangles have surface area 300. the pentagon's area 1/2*apothegm*sidelength*sides = 1/2*5.5*8*5 = 110. The total area is therefore 300+110 = 410
Lets take 100 and divide it by 4 to get 25, this means that 1 first part of 100 is 25 these means that the porcentage of 1 in 4 is 25%
Hope this helps
