Answer: The diameter of the pipe is 3.8 feet
.
Step-by-step explanation:
Hi to answer this question we have to apply the next formula:
Volume of a cylynder: π x r^2 x h
Where r is radius and h is height (length of the pipe in our case)
Replacing with the values given and solving for r:
100 = π x r^2 x9
100/ π x 9 = r^2
√(100/ π x 9) = r
r = 1.88
Since the diameter (D) is equal to:
D = 2r
D = 2 x 1.88 = 3.8 feet
The correct answer is D
The equation of a circle is (x-h)^2 + (y-k)^2 = r^2
to find (h,k), you find the middle of the circle, in this scenario you do so by finding the middle of the diameter, a line that goes through the center of the circle.
To find the X value of the midpoint, add both x values together and divide by 2 and repeat for y
-13 + -1 = -14
-14/2 =-7
10+ -6 = 4
4/2 = 2
therefore (h,k) = ( -7, 2 )
Next plug these values in the equation of a circle
(x-h)^2 + (y-k)^2 = r^2
becomes
(x- (-7)) ^2 + (y-(2)) ^2 = r^2
to find r, use the distance formula to find the length of the diameter, 20, and divide by 2
plug 10 in for r and you get 100
(x+7)^2 + (y-2)^2 = 100
sorry for the late response
Answer:
D.
Step-by-step & Reason explanation: This is really a general answer, it is actually really easy to answer. What you'd do is take whatever shape (like triangle ABC) and flip it over. When the question asks over the y-axis, you'll just flip it over to that side. I'm not sure if that made any since. But, think of it as a butterfly. You'll just throw it to the side the axis represents.
Thanks!
Answer:
5
Step-by-step explanation:
The diagonal is the length which is 5
solution
5 to the nearest tenth is 6
Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
Let's first establish the simple interest formula which we will require to solve this problem as displayed below:
Simple Interest = Principal × Rate of Interest × No. of Time Periods
I = PRN
Now let's substitute the values from the problem into this formula as displayed below:
I = $90
P = ?
R = 6%
N = 3 years
I = PRN
90 = P × 0.06 × 3
P = 90 / 0.06 × 3
P = 90 / 0.18
P = $500
ANSWER:
As the principal and the amount borrowed is the same, Claire borrowed $500. Therefore, the answer is:
D ) $500
