The perimeter of the shape is 94 cm and the area is 462 sq cm.
Step-by-step explanation:
Given,
The radius (r) = 14 cm
To find the area and perimeter of the given shape.
The given shape is 
of the full circle.
Formula
The perimeter of the circle = 2πr
The perimeter of the given shape = (2πr)+r+r = (2πr)+2r
The area of the circle = πr²
Now,
The perimeter of the given shape = (2×
×14)+2×14 = 94 cm
The area of the given shape = (πr²)
= ××14² = 462 sq cm

Cheetah ran 300 feet in 2.92 seconds.
Average speed in miles per hour.
Converting 300 feet to mile.
5280 feet = 1 mile
1 feet = (1/5280) mile
300 feet = (1/5280) * 300 = (300/5280) = (30/528) = (10/176) mile.
2.92 seconds to hour.
3600 seconds = 1 hour
1 second = (1/3600) hour
2.92 seconds = 2.92 * (1/3600) = (2.92/3600) hour.
Speed of Cheetah in miles per hour = (10/176) mile / (2.92/3600) hour
= 70.05 miles/hour
