Answer:

The circumference of the pool is 62.8 foot long and the area of the circle formed by the pool is 314 ft².

Step-by-step explanation:

The circumference of the pool can be found by calculating the arc's length of the edges of the pool. This is done by using the following formula:

circumference = 2*\pi*r

Where the radius is half the diameter, applying the data from the problem we have:

circumference = 2*3.14*10 = 62.8 \text{ ft}

The area of the circle formed by the pool can be found using the following expression:

area = pi*r^2 = 3.14*(10)^2 = 314 \text{ ft}^2

The circumference of the pool is 62.8 foot long and the area of the circle formed by the pool is 314 ft².

10 points!!! What is sqr root 12x^8/ sqr root 3x^2 in simplest form
marta [7]

Answer:

2 x^3

Step-by-step explanation:

sqrt(12 x^8)/ sqrt(3x^2)

combine into 1 term

sqrt(12x^8/3x^2)

when dividing exponents with the same base, we subtract

sqrt(12/3  x^(8-2))

sqrt(4 x^6)

sqrt(4)  sqrt(x^6)

2 x^3
