To solve, you'd have to find the area of the big circle(including walk way) and minus the ice rink.

Area of the big circle = 3.15(50)^{2} = 7850
Area of ice rink = 3.14(40)^{2} = 5024
7850 - 5024 = 2826

 The answer is about 2,826 square feet.

mr. smith has a maximum of $50 to spend at a museum. a ticket to the museum costs $7. he can spend p dollars to buy other things
7nadin3 [17]

The inequality that can be used to find the values for p is p + 7 ≤ 50.

Given the information,

Mr. Smith can only spend up to $50 at a museum. The museum admission ticket is $7. He can use his P dollars to purchase other items from the museum.

The total budget is $50.

The cost per ticket is $7

⇒ Total spent ≤  Total Budget

⇒ p + 7 ≤ 50

⇒ p ≤ 43

Therefore, p + 7 ≤ 50 will be the inequality that aids in determining the range of values for p.
