Answer:
603.2cm²
Step-by-step explanation:
SAshpere=4πr²
SAhemi=2πr²+πr²
2πr²+πr²=3πr²
3×π×8²=192π
=603.2cm²
Answer:
Step-by-step explanation:
Hope that this is helpful.
Add up the same sides of both equations to eliminate <em>x</em> :
(<em>x</em> - 2<em>y</em>) + (-<em>x</em> + 3<em>y</em>) = 8 + (-5)
(<em>x</em> - <em>x</em>) + (-2<em>y</em> + 3<em>y</em>) = 8 - 5
<em>y</em> = 3
Then
<em>x</em> - 2<em>y</em> = <em>x</em> - 6 = 8 → <em>x</em> = 14
For this problem plug in the given x and y values:
For the first one: No
second one: No
third one: Yes
fourth one: No
Answer:
C) Trapezoid
Step-by-step explanation:
Given
Required
The possible shape
The above are 4 vertices.
Hence, the shape cannot be
(a) Triangle ---- it has 3 vertices
(b) Pentagon ---- it has 5 vertices
Calculate distance AB using distance formula
Where:
Calculate distance BC using distance formula
Where:
Since
