Answer:
it's B
Step-by-step explanation:
because I did this
I still have absolutely no idea how it got that answer. Just move on and accept that the answer is still wrong no matter what
The surface area is A = 297.33
Answer:
25.13274125 in³
Step-by-step explanation:
The radius = 4 ± 0.1
height = 10
Volume of a cylinder = πr²h
Actual volume of the cylinder = π × 4² × 10
= 502.6548246
Maximum volume = π × 4.1² × 10
= 528.1017251
Minimum volume = π × 3.9² × 10
= 477.8362426
Average error = (528.1017251 - 477.8362426)/2
= 50.2654825/2
= 25.13274125 in³
The units are inches cubed.
Answer:
The triangle is obtuse.
It is an isosceles triangle.
The angles add up to 180°.
Step-by-step explanation:
Obtuse triangles are defined as triangles with one angle obtuse angle over 90°. This triangle has an angle of 100°, so it is an obtuse triangle!
Isosceles triangles have 2 equal sides. The two orange dashes on the left and right legs of the triangle tell us they are equivalent, so this is an isosceles triangle as well!
Finally, <em>all </em>triangles add up to 180°! We can prove this by adding the angles.
40° + 40° = 80°
100° + 80° = 180°
