Answer:
Radius = 7
Step-by-step explanation:
Since BA is tangent to circle O, it creates a 90° angle with the radius
Therefore, you can use Pythagorean theorem to solve this problem
a² + b² = c²
Let's say a is the radius
b is 5
c is 8.6
a² + 5² = 8.6²
a² + 25 = 73.96
Subtract 25 from both sides
a² = 48.96
Root both sides
a ≈ 6.997142274

Here is the answer
Answer:
16
Step-by-step explanation:
90/27 = 3
50/3 = 16
cuboid=3*3*5 [i.e l*b*h]
LCM of 3,5=15
i.e 15cm is the dimension of the final cube.
therefore cuboid required across length=15/3=5
similarly, across breadth=15/3=5
similarly, across height=15/5=3
Therefore total no of cuboid=5*5*3=75
For #2 it is. #4 it isn’t. #6 it isn’t.
