Answer:
7/9 or ~77.7778% or 0.777778
Step-by-step explanation:
First you need to find the total amount or marbles.
Next, find the sum of <em>just</em><em> </em>the<em> </em>blue<em> </em>and red marbles.
Now, find the probability by dividing or simplifying the number of blue and red by the total.
- 14/18= <u>7/9</u> OR <u>~</u><u>0</u><u>.</u><u>7</u><u>7</u><u>7</u><u>7</u><u>7</u><u>8</u>
Vertical, because when two angles are across from each other they are the same angle measurement.
We can separate this solid into two pieces: a cylinder and a cone. I will be finding the surface area's separately, then adding them together in the end.
Cylinder: The formula for the surface area of a cylinder is 2πrh+2πr². HOWEVER, since the cone and cylinder are connected, they don't count as part of the surface area, we don't need the 2 in 2πr². The radius, or r, is 5 cm. The height, or h, is 12 cm. Then, we use those numbers and plug it in the formula.
2πrh+πr²
2π(5)(12)+π(5)²
120π+25π
145π cm²
Cone<span>:
</span>
The surface area of the cone without its base is πrL where <em>r</em> is the radius (5) and <em>L</em> is the lateral side (13)
π·5·13=
65π
<u>Total</u><u>:</u> We add the total SA of the cylinder and cone together to find the total: 145π+65π =
210π cm²
