Please help need correct answer will give brainiest

perimeter of the fountain = 15π ft. or 47.1 ft. to the nearest 10th

Step-by-step explanation:

The semicircles have a circumference of 1/2πd = 1/2π(10) = 5π

Both semicircles together have a length of 5π + 5π = 10π

The radius of the 1/4 circle is 10, so the diameter is 20

The length of the 1/4 circle's arc is 1/4 times the circumference of its circle

So, the length of that arc is 1/4π(20) = 5π

Now the perimeter of the fountain is 10π + 5π = 15π

i am sure it will be 90 degrees.

step-by-step explanation:

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4
