Answer:
About 163 (Exact Answer: 163.1)
<h2>
Step-by-step explanation:</h2>
11.3s + 10.5t
Replace s with 7 and t with 8.
11.3(7) + 10.5(8)
Multiply.
11.3(7) + 10.5(8) =
79.1 + 84
Add.
79.1 + 84=
163.1 ≈ 163

We know that
volume of a right circular cylinder=pi*r²*h
where
r ----> is the radius
h---> is the height
in this problem
r=6 cm
h=?
Volume=550 cm³
so
V=pi*r²*h------> h=V/[pi*r²]----> h=550/[3.14*6²]----> h=4.87 cm
<span>Round to the nearest tenth
</span>h=4.9 cm
the answer is
4.9 cm
Answer:
66/125
Step-by-step explanation:
Divide top ad bottom by 8. The resulting fraction cannot be simplified further.
The midpoint lines are half the opposite side length.
Line DE is given as 7 , So Line F = 7 x 2 = 14
Line EF is given as 12, so Line D = 12 x 2 = 24
Line DF is given as 16, so line E = 16 x 2 = 32
The perimeter is the sum of the 3 sides:
Perimeter = 14 + 24 + 32 = 70
