Answer:
it's B I think because I worked it out and I got B
<span>The volume of the cylinder will be 2</span>π
As shown in figure, R is the base
radius of the cylinder.
H is the height of the cylinder.
Given: H = diameter of the base of
cylinder.
Now, diameter of the base = 2R
So, H = 2R
<span>Volume of cylinder = π×</span>
×H
<span> = π×</span>×(2R)
<span> = 2 π </span> cubic units.
Answer:
Always
Step-by-step explanation:
Subtracting a from both sides yields b>0, which is always true since b is a positive integer.

Answer:
(a) 8 km
Step-by-step explanation:
Let m represent the distance (in kilometers) Michelle has walked. Then Janet walked a distance of (m-2). These distances are at right angles, so the distance between them can be found using the Pythagorean theorem.
m² +(m -2)² = 10²
m² +m² -4m +4 = 100
2m² -4m = 96 . . . . . . subtract 4, collect terms
m² -2m +1 = 49 . . . . . divide by 2 and add 1
(m -1)² = 7² . . . . . . .write as squares
m -1 = 7 . . . . . . positive square root
m = 8
Michelle walked 8 km.
