Attempt following question by selecting a choice to answer.
D
The diameter of a circular garden is 44 ft. What is the new circumference of the garden, if its radius is decreased by
6 ft? [ Use π = 3.14]cc DDA.
D102.48 ft
B.
D100.48 ft
C.
D104.48 ft
D.
D200.96 ft
D
B
Step 1: The diameter of the circular garden = 44 ft.
Step 2: So, the radius of the circular garden = diameter2 = 442 = 22 ft.
Step 3: If the radius is decreased by 6 ft, then the new radius = 22 - 6 = 16 ft.
Step 4: The new circumference of the garden = 2 × π × new radius. [Formula.]
Step 5: [Substitute the values.]
= 2 × 3.14 × 16
Step 6: [Multiply.]
= 100.48 ft.
Step 7: So, the new circumference of the garden = 100.48 ft.
