Question

find the circumference and the area of a circle with radius 5 yd. use the value 3.14 for π, and do not round your answers. be sure

Explanation:

Step1: Calculate Circumference

The formula for the circumference of a circle is \( C = 2\pi r \). Given \( r = 5 \) yd and \( \pi = 3.14 \), substitute the values:
\( C = 2\times3.14\times5 \)
\( C = 31.4 \) yd

Step2: Calculate Area

The formula for the area of a circle is \( A = \pi r^2 \). Substitute \( r = 5 \) yd and \( \pi = 3.14 \):
\( A = 3.14\times5^2 \)
\( A = 3.14\times25 \)
\( A = 78.5 \) square yards

Answer:

Circumference: \( 31.4 \) yd, Area: \( 78.5 \) square yards
