Answer:
V ≈ 263.9 units³
Step-by-step explanation:
The volume (V) of a cone is calculated as
V =
πr²h ( r is the radius and h the height )
Here r = 6 and h = 7 , then
V =
π × 6² × 7
=
π × 36 × 7
=
π × 252
= 84 π
≈ 263.9 units³ ( to 1 dec. place )
Answer:
B.
Step-by-step explanation:
The symbol between JK and LM mean that they are perpendicular, it is, that at their intersection 90 degrees angles are formed (those are right angles). So, the correct option here is option B. JK and LM meet at a right angle.
Here I attach a dray of how an intersection like this must look like. I hope it is helpful for you. In the draw four right angles are formed, however, this is not necessary, coul be only one or two depending on the length of the lines segments.
Let x = our unknown number
10x = 600
Divide by 10 on both sides to isolate the variable x.
x = 600/10
x = 60
600 is 10 times as much as 60.
