Compare Circumferences: Circle A (8cm) vs Circle B (2cm) Diameter Problem

Let's solve the problem step-by-step:

• Step 1: Calculate the circumference of circle A.
• Step 2: Calculate the circumference of circle B.
• Step 3: Compare the circumferences to determine which is larger.

Now, let's calculate each one:

Step 1: The circumference of circle A is calculated as follows:

Using the formula $C = \pi \times d$,

$C_A = \pi \times 8 = 8\pi$ cm.

Step 2: The circumference of circle B is calculated in the same manner:

Using the same formula $C = \pi \times d$,

$C_B = \pi \times 2 = 2\pi$ cm.

Step 3: Compare the circumferences:

Since $8\pi$ cm (Circle A) is clearly greater than $2\pi$ cm (Circle B), the circle with a larger circumference is Circle A.

Therefore, the circle with a larger circumference is Circle A.
