Answer: C=14π≈43.98 ft
Step-by-step explanation:
To find the circumference of the circle, we use the equation C=2πr or C=πd. These 2 equations are equivalent because 2r is the same as d, diameter. In this case, we can use C=πd because the problems already gives us the diameter.
C=πd
C=14π≈43.98 ft
I hope this helps!
On Part A you have to subtract $2.39-$1.99. Then in Part B you have to multiply $4.50 by 2. And then I think you have to add $3.79 when u are done multiplying.
It’s b i’ve had this before
Answer:
Option (B)
Step-by-step explanation:
CDEF is a quadrilateral having vertex C(2, 3), D(1, 2), E(4, 1), F(5, 3).
To prove that the given quadrilateral has a right angle, we will use the property of perpendicular lines.
where 
and 
are the slopes of the consecutive sides of the quadrilateral.
Since CD and DE are the consecutive sides of the quadrilateral, Carla is on the right track by finding the slopes of CD and DE.
Since Jonah is finding the slopes of opposite sides so he will not be able to use the property of perpendicular lines.
Option (B) will be the answer.
Find the volume of each size stack by multiplying Length x width x height.
Once you have the volume for the 3 different stacks of books, add the together.
Bottom: 12 x 1 x 6 = 72 cubic inches per book x 2 = 144 cubic inches total.
Middle: 10 x 1 x 5 = 50 cubic inches per book x 2 = 100 cubic inches total.
Top: 7 x 0.5 x 4 = 14 cubic inches per book x 2 = 28 cubic inches total.
Total volume = 144 + 100 + 28 = 272 cubic inches.
