The square footage of the path is 47.1 ft²
The area of a circle is:
A = πr²
Where r is the radius of the circle.
Let us assume that the pool is a circle.
Given that the pool has a radius (r₁) of 7 feet and a path 1 foot wide would go round the pool.
Radius of pool and cement path (r₂) = 7 ft + 1 ft = 8 ft.
The square footage of the path = πr₂² - πr₁² = π*8² - π * 7² = 47.1 ft²
Hence The square footage of the path is 47.1 ft²

Answer:
1/8
Step-by-step explanation:
Kylie's little brother ate 1/4 of 1/2 of the cake. This means he ate 1/8 of the whole cake, since 1/2 is 0.5 of the whole cake, and that means that to find the fraction of what her brother ate, you must divide 1/4 in half, which is 1/8.
