X=22
Area is found by multiplying (x+7)and (2x-1) together. 22+7=29, 2(22) -1 = 43, 43+29=72
One rotation means going once through a circular route.
One circular route means turning around by 360°
Now we know that one rotation always makes 360°.
The hard disk rotates 256 times in 1 second.
First we shall calculate the number of degrees.
In one rotation it covers 360°.
So in 256 rotations it covers 256 × 360 = 92160°
But these 256 rotations are made in one second.
So the disk passes 92160° in one second.
Answer: The hard disk passes 92160° in one second
Answer:
339, 340, 341
Step-by-step explanation:
To find the 3 consecutive numbers, divide the sum by 3 to get the average. 1020/3=340. So the middle number is 340. That means the numbers are 339, 340, and 341.

Answer:
r = 19 ft
Step-by-step explanation:
Circumference, C is given as 119.32 ft
Circumference of a circle is given by the formula, 2πr
This means that,
C = 2πr, we're told to assume that π = 3.14
So therefore,
119.32 = 2 * 3.14 * r
r = 119.32 / 6.28
r = 19 ft
