Answer:
Step-by-step explanation:
Circumference = C = 31.4 ft
We know that,
<h3>C = 2πr</h3>Where, r is the radius
31.4 = 2(3.14)r
31.4 = 6.28(r)
Divide 6.28 to both sides
31.4/6.28 = r
5 ft. = r
<h3>r = 5 ft.</h3>Now,
<h3><u>Finding area:</u></h3>A = πr²
A = (3.14)(5)²
A = (3.14)(25)
<h3>A = 78.5 ft²</h3>
So, she buys 16 bags, each of them weights
pounds.
to find how many pounds of soil she bought, we have to multiply:
16*=//16 is equal to 8*2, so we can simpify:
2*
which is 2*5=10
so in the end she bought 10 pounds of soil!
