The length of CS is 11.0
Explanation:
Given that the length of the tangent AR is 12
The length of SR is 7.7
To find: The length of CS
The<u> tangent secant theorem</u> states that "if a tangent and a secant are drawn from an external point to a circle, then the square of the measure of the tangent is equal to the product of the measures of the secant’s external part and the entire secant."
Applying the tangent secant theorem, we have,
Rewriting the above equation, we get,
Substituting the values, we get,
Simplifying, we have,
Subtracting both sides by 59.29, we get,
Dividing both sides by 7.7, we have,
Rounding off to the nearest tenth, we get,
Thus, the length of CS is 11.0
By using scientific notation we calculated (2.310⁵)(1.5
10⁴) we got 345
10⁷.
Given that,
(2.310⁵)(1.5
10⁴)
By using scientific notation
The scientific notation allows us to express extremely large or extremely small numbers by multiplying them by single-digit integers and by 10 raised to the power of the corresponding exponent. The exponent is either positive or negative depending on how big or little the number is.
Now, we calculate
(2.310⁵)=2.5
100000=230000
(1.5 10⁴)=1.5
10000=15000
Now,
=23000015000
=3450000000
=345 10⁷
Therefore, By using scientific notation we calculated (2.310⁵)(1.5
10⁴) we got 345
10⁷.
