Question

circumference and area of a circle with radius of 27, use 3.14 for pi

Answer 1

To calculate the circumference and area of a circle with a radius of 27, using \( \pi \approx 3.14 \):

1. **Circumference (C)**:
The formula for the circumference of a circle is:
\[
C = 2 \pi r
\]
Substituting the values:
\[
C = 2 \times 3.14 \times 27
\]
\[
C = 6.28 \times 27 = 169.56
\]

2. **Area (A)**:
The formula for the area of a circle is:
\[
A = \pi r^2
\]
Substituting the values:
\[
A = 3.14 \times (27)^2
\]
\[
A = 3.14 \times 729 = 2290.26
\]

So, the **circumference** of the circle is approximately **169.56**, and the **area** is approximately **2290.26**.
