Ruby is visiting a wildlife center to gather information for her term paper. the center has a circular pond with a diameter of 20 meters. what is the approximate area of the pond?

Area of pond = 314 meter².

Step-by-step explanation:

Given  : The center has a circular pond with a diameter of 20 meters.

To find : What is the approximate area of the pond.

Solution: We have given  diameter =  20 meters.

Radius = .

Radius =  .

Radius = 10 meter .

Area of circular pond = pi ( radius) ².

Area of pond = 3.14  (10) ².

Area of pond = 3.14 * 100.

Area of pond = 314 meter².

Therefore, Area of pond = 314 meter².

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
