Decimals and fractions are alike because all decimals are fractions and all fractions are decimals. As an example: 1/2, which is one-half, is the same as 0.5.
Answer:
Perimeter = 13*pi + 26 = 66.84 units
Step-by-step explanation:
Let us find the circumference.
C = 2*pi*r
C = pi*26
half circle length = (1/2)*C = 1/2*pi*26 = 13*pi
Perimeter must include the diameter length
Perimeter = 13*pi + 26 = 66.84 units

Answer:
it would be 9/12
Step-by-step explanation:
if you want to get a denominator of 12 you would have to multiply by 3 from both and you should get 9/12. 3*3=9 and 4*3=12.
