Answer:
x= 6.5 cm
Step-by-step explanation:
When a tangent line touches the circle, it forms a right angle triangle at that point
Apply the Pythagorean relationship in this case
Given that the height is = 20.2 cm = b
The hypotenuse is = c= x+14.7 cm
General formulae is;
a² +b² =c²
x² + 20.2² =( x+ 14.7)²
x² + 408.04= x² +14.7x+14.7x+216.09
x² + 408.04= x² + 29.4 x +216.09.........................collect like terms
x²-x² + 408.04-216.09= 29.4x
191.95= 29.4x-------------------------------divide by 29.4 t0 get x
191.95/29.4 =x
x=6.5 cm
there is not enough info given to tell how long it would take
Answer:
x = 34
Step-by-step explanation:
Just add 14 on both sides of the equal sign to get x = 34.
Hope this helps :)
The answer is one thousand five hundred thirty eight
Answer:
Option B is correct
circumference of a circle is 785 m
Step-by-step explanation:
Circumference of the circle(C) is given by:
where
r is the radius of the circle
As per the statement:
radius of the circle is 125 m
then substitute in [1] we have
Simplify:
C = 785 m
Therefore, the circumference of a circle is 785 m
