I think 6 because it’s a ratio
Because the yellow would always be twice as much as the red so 3x2 is 6 just like 6x2=12
Answer:
C and D
Step-by-step explanation:
Mathematically, a unit circle is one in which the value of the radius is 1 unit
Generally, for a unit circle we have it that;
r^2 = x^2 + y^2
where (x,y) represents the coordinates of a point on the unit circle
But from above, r = 1
Thus:
x^2 + y^2 = 1
Looking at option C, by squaring each coordinate, we have
(6/7)^2 = 36/49 and the second as 13/49
by adding both, we have
36/49 + 13/49 = 49/49 = 1
Thus, we have this as a coordinate on the unit circle
For the last option;
(5/13)^2 = 25/169 and (12/13)^2 = 144/169
Adding both, we have;
25/169 + 144/169 = 169/169 = 1
So this is also a point on the unit circle
Answer:
Step-by-step explanation:
6/2=3 cm is the radius V(4/3πr³) = 4/3.π.27…(1)
8/2= 4 cm is the radius and V = 4/3.π.64…..(2)
10/2=5 cm is the radius and V = 4/3.π.125…(3)
The Total Volume is the addition of (1)+(2)+(3) or 4/3π (27+64+125) or New volume is 4/3.π.(216) cm³ and therefore...
The radius of the New Solid Sphere is Cube Root of 216 (r³) = √6.6.6 or r = 6 cm and the diameter is 6.2 = 12 cms.
12 cms answer. Brainlist please?
Answer:
252pi (B)
Step-by-step explanation:
Find the area of the bases (2 * pi * r^2)
r = 6, so:
72pi = total area of bases
Find the area of the side (pi * 2 * r * h)
r = 6 and 15 = h, so:
180 pi = area of the side
180pi + 72pi = 252pi (B)
