Answer:
using V=w x h x l=11·12·3=396
Step-by-step explanation:
396 cm^3
The dimensions of the rectangles to the nearest hundredth are
- length = 13.56 inches
- width = 3.39 inches
<h3>What is a rectangle?</h3>
A rectangle is four sided plane figure which each pair of sides equal and opposite to each other. The sides intersect at an angle of 90 degrees.
<u>Given data</u>
Area of the rectangle = 46 square inches
length L = 4 * width W
area of a rectangle, A
A = L * W
46 = L * W
46 = 4w * w
46 = 4w^2
w^2 = 11.5
w = sqrt ( 11.5 )
w = 3.391 inches
w = 3.39 to the nearest hundredth
since L = 4w
L = 4 * 3.391
L = 13.564
L = 13.56 to the nearest hundredth

Answer:
y+4
Step-by-step explanation:
Answer:
About 126 ft/min
Step-by-step explanation:
We know r = 2 feet, and that the wheel has an angular speed of 10 rpms, or 10 revolutions per minute. Our goal is to get the speed in ft/sec.
10 rev 1 minute 2π radians 2 feet
----------- × ---------------- × ------------------ × ------------
1 minute 60 seconds 1 revolution 1 radian
= 10 * 2π * 2 = 126 ft/minute
The answer is reasonable. Another, simple approach to this would be using the formula 2π * r * rpm. If so, 2π * 2 * 10 which would be 126 ft/minute.
