Studdy Solution

STEP 1

STEP 2

Recordar la fórmula para la circunferencia de un círculo:
C=2πr C = 2\pi r

STEP 3

Sustituir el valor del radio en la fórmula:
C=2π×12.1 C = 2\pi \times 12.1

STEP 4

Calcular la circunferencia:
C=2π×12.1 C = 2\pi \times 12.1 C2×3.1416×12.1 C \approx 2 \times 3.1416 \times 12.1 C76.02672 C \approx 76.02672

STEP 5

Redondear la respuesta al décimo más cercano:
C76.0 C \approx 76.0
La circunferencia del círculo es:
76.0 ft \boxed{76.0 \text{ ft}}
