ANSWER
10.0 ------- Vivian is correct
EXPLANATION
Firstly, find the cube root of 1010
In the above calculation, the cube root of 1010 is 10.003
The correct approximation of the above value is 10.0. This is because the hundredth value is not upto 5
Recall, figures from 1 - 4 are rounded to zero and figures from 5- 9 are rounded up to 1
since 3 is not upto 5, so it is rounded down to zero
Therefore, Vivian is correct

Answer:
Step-by-step explanation:
The perimeter of a polygon is equal to the sum of all the sides of the polygon. Quadrilateral PTOS consists of sides TP, SP, TO, and SO.
Since TO and SO are both radii of the circle, they must be equal. Thus, since TO is given as 10 cm, SO will also be 10 cm.
To find TP and SP, we can use the Pythagorean Theorem. Since they are tangents, they intersect the circle at a , creating right triangles
and
.
The Pythagorean Theorem states that the following is true for any right triangle:
, where
is the hypotenuse, or the longest side, of the triangle
Thus, we have:
Since both TP and SP are tangents of the circle and extend to the same point P, they will be equal.
What we know:
Thus, the perimeter of the quadrilateral PTOS is equal to
