Find the area of a circle with a circumference of 31.5 units

Westkost [7]

Answer:

79 units²

Step-by-step explanation:

The area of a circle is found by using the formula A = π x r². Since we are not given the radius we can use the formula r = C / (2π). Substituting in the given values, we get r = 31.5/(2π). 2 times pi is 6.283185307. 31.5 divided by this will get you 5.013380707. Now, put that value in for r in the area equation. A = π x 5.013380707². Pi times 5.013380707² equals 78.96074613. This can be rounded to 79. (Or 80 if you need to the nearest whole number.)

Your class hopes to collect at least 325 cans of food for the annual food drive. there were 135 cans donated the first week and

vampirchik [111]

They have collected $135+89=224$ cans until now. To equal 325, they need $325-224=101$ cans more.

Let C be the number needed to equate atleast 325.

$135+89+C\geq 325$

If we solve the inequality in part A, we can find minimum number of C to meet the goal of 325 cans.

$135+89+C\geq 325\\224+C\geq325\\C\geq325-224\\C\geq101$

<em>So they need minimum 101 to complete the target and more than that to surpass.</em>

ANSWER: 101 cans are needed to meet the goal and more than that to surpass the goal.
