Question

the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your answer. a gardener makes a new circular flower bed. the bed is ten feet in diameter. calculate the circumference and the area of the circular flower bed.
circumference = 10 feet, area = 10π square feet
circumference = 10π feet, area = 100π square feet
circumference = 5π feet, area = 25π square feet
circumference = 10π feet, area = 25π square feet

Explanation:

Step1: Recall formulas for circle

Circumference of a circle: \( C = \pi d \) (where \( d \) is diameter). Area of a circle: \( A = \pi r^2 \) (where \( r \) is radius, \( r=\frac{d}{2} \)).

Step2: Calculate circumference

Given \( d = 10 \) feet, so \( C=\pi\times10 = 10\pi \) feet.

Step3: Calculate radius

Radius \( r=\frac{d}{2}=\frac{10}{2}=5 \) feet.

Step4: Calculate area

Substitute \( r = 5 \) into area formula: \( A=\pi\times5^2=\pi\times25 = 25\pi \) square feet.

Answer:

D. circumference = \( 10\pi \) feet, area = \( 25\pi \) square feet
