Answer:
(6.25[tex]\pi[/tex] + 25)cm is the exact answer
44.625 cm is an approximation
Step-by-step explanation:
c = circumference (perimeter)
d = diameter
C = [tex]\frac{\pi d}{4}[/tex]
C = [tex]\frac{25\pi }{4}[/tex] = 6.25[tex]\pi[/tex] This is the exact answer
That would be the curved part of the pi. Then we need to add the 2 sides which would be [tex]\frac{25}{2}[/tex] + [tex]\frac{25}{2}[/tex] = [tex]\frac{50}{2}[/tex] = 25 The sides are the length of the radius which is half of the diameter.
(6.25[tex]\pi[/tex] + 25)cm is the exact answer
If we use 3.14 for [tex]\pi[/tex] The approximate answer would be:
6.25(3.14) + 25
19.625 + 25
44.625 cm is an approximation
