Answer:
Perimeter = 15 cm
Step-by-step explanation:
The equation P=5s represents the perimeter P of a regular pentagon with side length s.
We need to find the perimeter of a regular pentagon with side length of 3 cm.
To find it, put s = 3 cm in the given equation.
P = 5(3) cm
= 15 cm
Hence, the perimeter of the regular pentagon of side length 3 cm is 15 cm.
Answer:
61.973
Step-by-step explanation:
let the unknow side be x
surf of prism = 2*(8*8+8x+8x) = 2*(64+16x) = 128+ 32x
again, surface of cylinder = 2pi*r*(r+h) = 2 * pi * 14 * (14+10) = 672pi
now solve for x, when
128+32x = 672pi
8 15 17 i think no clue really
32/80 so divide that by 5 = 6.4/20 then multipy that by 100/1 so the answer is 640
