A)106°- angle at the centre is half of the angle at the circumference
b)74°- when a tangent meets a radius a right angle is created(90+90+106)= 286 360-286= 74°
The difference between -8 F and 14 F is 22 F.
Answer:
-10
Step-by-step explanation:
-2 + ? = -12
+2 +2
?= -10
The volume of a cylinder is given by πr²h where, r is the radius of the cylinder and <span>h </span>is the height of the cylinder.
Also<span> r=d/2</span> , where d is the diameter of the cylinder.
Therefore if the diameter is halved, the radius also gets halved ,i.e., it becomes r/2. Therefore the new volume =<span> π(r/2)²h</span>
=π(r²/4)h
<span>=(1/4) πr²h</span>
<span>
</span>
The answer is A) DE. I really don’t know how to explain this. Just remember the definition of parallel lines and you’ll see it.
