Question 3 options: lily is building a picture frame. the larger rectangle represents the frame. the smaller rectangle represent
Finger [1]

The area of the shaded region of this figure which can be calculated by the difference of the larger region from the smaller region would be 104 in.²

<h3>What is the area of the rectangle?</h3>

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

Area of a larger rectangle

= Length × Width

= 18 × 12

= 216 in.²

Area of the smaller rectangle

Length = 12 - 2 - 2 = 8 in.

Width = 18 - 2 - 2 = 14 in.

= Length × Width

= 8 × 14

= 112 in.²

Area of the shaded region = Area of a larger rectangle - Area of the smaller rectangle

= 216 - 112

= 104 in.²

Hence, the area of the shaded region of this figure is 104 in.²

A cyclist is riding a bicycle whose wheels have a diameter of feet. Suppose the wheels turn at a rate of revolutions per minute.
SCORPION-xisa [38]

Answer:

a.2010 rad/min

b.2412 feet/min

Step-by-step explanation:

We are given that

Diameter of wheel,d=2.4 feet

Radius,r=\frac{d}{2}=\frac{2.4}{2}=1.2feet

a.Rate=320 rev/minute

1 rev=2\pi radian

320 rev/minute=320\times 2\pi=640\pi radian/minute

Where \pi=3.14

Angular speed=640\times 3.14=2010 rad/min

b.Speed,v=r\omega

v=2010\times 1.2=2412 feet/min
