Answer: Four-thirdsπ(6)³
Step-by-step explanation: The formula for the volume of a sphere is attached in the image down below.
Notice that two of the options listed have <em>three-fourths</em> but we use <em>four-thirds </em>to find the volume of a sphere. This means that we can eliminate the 1st and the 3rd option.
Now, we will multiply that by π and then by the radius cubed which is also written as 6³. This means that our answer would be the second option.
A 90
In a regular shape all of the sides an angles are the same
360/4=90
Tanx=85
Sin85=0.100
I hope my answer will be helpful to you
Answer:
55°
Step-by-step explanation:
Since ΔABC is right we can use the tangent ratio to find ∠B
tanB =
=
, hence
B =
(
) = 55°
