An explanation is required or else not brainliest.

16 meters

Step-by-step explanation:

is tangent to the circle at point R and FR is radius.

(Tangent radius theorem)

So, is right angled triangle and FS is its hypotenuse.

Let FR = FT = r

FS = FT + ST = r + 9

Now, by Pythagoras theorem:

Thus, the diameter of the fountain is 16 meters.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
