Question

question 5 of 10
what is the approximate area of a circle with a radius of 11 m?
a. 34.5 m²
b. 69 m²
c. 380 m²
d. 190 m²

Explanation:

Step1: Recall area formula

$A = \pi r^{2}$

Step2: Substitute radius value

$A=\pi\times(11)^{2}=\pi\times121$

Step3: Approximate $\pi$

Take $\pi\approx 3.14$, then $A\approx3.14\times121 = 379.94\approx380\ m^{2}$

Answer:

C. $380\ m^{2}$
