Question

Julie and her brother go to Atlanta to ride the SkyView Ferris wheel. It measures 200 feet in diameter.

Answer 1

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
