Answer:
Small one is 4ft larger one is 12ft
We have to calculate the perimeter of the figure to the nearest tenth of a millimeter. This figure is made of a rectangle and a half of a circle. The first figure has the perimeter: 3 + 6 + 3 = 12 mm. The second figure has the perimeter: 2 * Pi * r / 2 = Pi * r ; and the radius : r = 6/2 = 3 mm. So Pi * 3 = 3.14 * 3 = 9.42. Fimally : 12 + 9.42 = 21.42 or 21.4 to the nearest tenth. Answer: C. 21.4 millimeters<span>. </span>
Answer:
4 1/12 sq. ft
Step-by-step explanation:
To know the amount of area that Pete’s bed have more than Fluffy’s bed, we simply calculate the area of both beds then subtract the smaller from the larger.
The area of Fluff’s bed would be 3 * 21/12 = 63/12 Sq ft
The area of Pete’s bed would be 4 * 28/12 = 112/12 sq ft
The difference in area is thus: 112/12 - 63/12 = 49/12 = 4 1/12 sq. ft
