Answer: 76.35in²
Step-by-step explanation:
Circumference of a circle = 2πr or πd , while area is πr².
To find the area we must first of all find the radius if the circle using any of the formula above.we then equate 31 to 2πr and then solve for r.
31 = 2πr , where π = 3.142 or 22/7
r = 31/2 x 3.142
= 31 /6.284
= 4.93in
To find the area, substitute for r in the formula above,
Area = πr²
= 3.142 x 4.93²
= 3.142 x 24.30
= 76.35in².
Answer:
168 adult tickets were sold
Step-by-step explanation:
Multiply the amount of students by the cost of the student ticket (82 times 3.75) which equals 307.5 . Subtract that from the total amount earned (2071.5) and you get 1764. Divide that by the cost of an adult ticket (10.50), and you'll get the amount of adults who attended, which is 168.
