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:
For a given x, the value on the blue line is about 1/2 the value on the black line. The appropriate choice is
y = (1/2)x
Answer:
It's 96
Step-by-step explanation:
-<u>The left and right rectangles</u>
5*4=20
(5*4)*2=40
-<u>Triangle</u> (front and back)
8*3/2=12
(8*3)/2*2=24
-<u>Bottom Triangle (base</u>)
8*4=32
<u>-Area</u>
=40+24+32
=<em>96</em>
Answer:
Scale factor = ½
Step-by-step explanation:
The original image is the preimage = ∆ACB
The new image is the image = ∆DFE
The scale of factor of dilation = image/preimage = DF/AC
DF = 6 cm (given)
AC = 12 cm (given)
Plug in the values into the equation to find the scale factor of dilation:
Scale factor = 6/12
Scale factor = ½
