Answer:
9) Vincent will not get the correct answer because the + 484 is unneccesary, as he already subtracted it.
10a) 310,000 + x = 465,000; so x = 155,000
10b) 930,000/310,000 = 3 times more
Step-by-step explanation:
Honey where are the triangles??
Let x = smaller number
Let y = bigger number
y = 7x + 4
x + y = 92
x + (7x + 4) = 92
8x + 4 = 92
8x = 88
x = 11
y = 7x + 4
y = 81

Answer:
volume of a hemisphere ≈ 36369.5 in³
Step-by-step explanation:
To find the formula for calculating the volume of a hemisphere, we will follow the steps below:
write the formula for calculating the volume of a hemisphere.
volume of a hemisphere = volume of a sphere ÷2
=
πr³ ÷ 2
=
πr³
where r is the radius
from the question given, diameter = 51.8 inches
but diameter = 2r , this implies that r =
hence r =
= 25.9 inches
π is a constant and is ≈ 3.14
we can now proceed to insert the values into the formula
volume of a hemisphere =
πr³
=
× 3.14 ×25.9³
=
× 3.14×17373.979
≈36369.5 in³ to the nearest tenth cubic inch.
volume of a hemisphere ≈ 36369.5 in³
