Answer:
Question 1: A)we need to use the CIRCUMFERENCE.
B) Circumference of a Circle = 2 π R
c)The distance traveled in 1 rotation = 628 ft
2(a)AREA of a CIRCLE = π R²
(b)Area the wheel takes up is 31,400 sq ft
Step-by-step explanation:
Question 1:
Diameter = 200 ft
Now,as Diameter = 2 x Radius
So, R = D/2 =200/2 = 100 ft
A) Distance around the wheel = The length of the boundary of the wheel.
So, we need to use the CIRCUMFERENCE.
B) Circumference of a Circle = 2 π R
Here R = Radius and use π = 3.14
C) The distance traveled in 1 rotation = 1 completer length of boundary
Now, Circumference = 2 π R = 2 x (3.14) x (100 ft) = 628 ft
Question 2:
A) Space the Ferris Wheel takes up = Area of the wheel
AREA of a CIRCLE = π R²
B) AREA of a CIRCLE = π R²
= (3.14) (100 ft ) (100 ft) = 31,400 sq ft
So, the area the wheel takes us is 31,400 sq ft
