Do you mean answer? Well, here is the answer: 211
Hope this helps! You should always make sure you know your division! :)
Step-by-step explanation:
the lateral area of the cone is, well, the lateral area.
the total surface area of the cone is the lateral area plus the area of base circle.
so, the difference between both is the area of the base circle :
120pi - 70pi = 50pi
the area of a circle is
pi×radius²
and that is in our case
pi×radius² = 50pi
radius² = 50
radius = sqrt(50) = 7.071067812... ≈ 7.1 units
therefore, C is the right answer.
The dash on each side of the triangle show that those three sides have the same measurement. Therefore, divide 24 by 3 to get 8, which is the measurement for each side of the triangle.
Meaning your answer is:
a. 8cm, 8cm, 8cm
Option C:
x < –2 (or) x ≥ 4
Solution:
To find which compound inequality is represented by the graph:
Note:
If the circle is filled, then use ≤ or ≥.
If the circle is not filled, then use < or >.
In the given graph,
–5, –4, –3 are lesser than –2 and 5 is greater than 4.
–2 > x (or) 4 ≤ x
i.e x < –2 (or) x ≥ 4
Here the circle is not filled for –2, so use strictly less than symbol.
The circle is filled for 4, so use greater than or equal to symbol.
Option C is the correct answer.
Hence x < –2 (or) x ≥ 4 is the compound inequality represented by the graph.
The area of the parallelogram is 78
