Answer:
200.96 feet
Step-by-step explanation:
We have a pool with a radius of 28 feet.
They also tell us that there is a path around the pool and its width is 4 feet.
Thus:
The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.
= (28 + 4) feet
= 32 feet
To find the length of the fence, we need to find the circumference of the outside of the pool path. The radius is then equal to 32 feet.
The circumference of the outer edge of the pool path would be equal to the perimeter.
p = 2 * pi * r
replacing
p = 2 * 3.14 * 32
p = 200.96 feet
therefore 200.96 feet are needed
If this helps please considering giving me brainliest as it helps me a lot.
232-(59+57+58) = S
232-174 = S
S = 58
Hope this helps!
First, let us define our variables.
Let
x = age of the father
y = age of the son
z = age of the daughter
5 years ago..
(x – 5) = age of the father
(y – 5) = age of the son
(z – 5) = age of the daughter
After 18 years...
(x + 18) = age of the father
(y + 18) = age of the son
(z +18) = age of the daughter
From the first condition
y = z + 5 à
eqn 1
5 years ago
(x-5) = 23 + (y-5) + (z-5)
x –y –z = 18 à
eqn 2
after 18 years
(x+18) = 17*[(y +18 –z – 18)]
x – 17y + 17z = -18 à
eqn 3
solving the 3 equations simultaneously
x = 67
y = 27
z = 22
