Question

riley is covering a circular pool with a tarp. the pool has a radius of 13 feet. approximately how much of the pool does riley need to cover with a tarp? solve on paper. then, enter your answer on zearn. remember, you can use 3.14 as an approximation for π. consider writing your answer to the hundredths place. riley needs to cover approximately square feet with a tarp.

Explanation:

Step1: Recall area formula for circle

The formula for the area of a circle is $A = \pi r^{2}$, where $r$ is the radius.

Step2: Substitute given radius

Given $r = 13$ feet and $\pi\approx3.14$, we have $A=3.14\times13^{2}$.

Step3: Calculate $13^{2}$

$13^{2}=13\times13 = 169$.

Step4: Multiply by $\pi$ approximation

$A = 3.14\times169=530.66$ square - feet.

Answer:

$530.66$
