Answer:
The best estimate for rounding is 0.9, but if you are simplifying the fraction it should be 9/10
Step-by-step explanation:
diameter = 2 * radius
= 2 * 44
= 88 cm (ANS)
Answer:
The correct answer is second option
3π in²
Step-by-step explanation:
<u>Points to remember</u>
Area of circle = πr²
Where r is the radius of the circle
<u>To find the area of outer ring</u>
Here radius of large circle = 1 + 1 = 2 in and
radius of small circle = 1 in
Area of outer ring = Area of large circle - area of small circle
= π2² - π1²
= 4π - π
= 3π in²
The correct answer is second option
3π in²
Answer:
<h2>The time needed is 10 months.</h2>
Step-by-step explanation:
The given points are (0, 3500) and (5, 1750).
First, we use the formula below to find the slope of the line
Which means the function is deacrasing with a ratio of 350 feet per month.
Now, we use the slope and one point to find the equation
This linear function shows that the situation started at the y-intecept (0, 3500), which means the month 0 had already 3500 feet. In other words, the total distance is 3500 feet. Now, the x-intercept will tell us the time needed to travel that distance.
Therefore, the time needed is 10 months.
