The area and the circumference of the circle are 530.93 square ft and 81.68 ft. If fertilizer will be applied to the lawn. Then the area is used. If the lawn will be surrounded by tape. Then the circumference is used.
<h3>What is a circle?</h3>
It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.
The figure below shows a circular lawn. Its diameter is 26 ft.
Then the area of the circle will be
Then the circumference of the circle will be
Circumference = π d
Circumference = π × 26
Circumference = 81.68 ft
If fertilizer will be applied to the lawn. Then the area is used.
If the lawn will be surrounded by tape. Then the circumference is used.

Answer:
Step-by-step explanation:
The greatest common factor is the greatest factor common to all terms. An expression is completely factored when no further factoring is possible. The possibility of factoring by grouping exists when an expression contains four or more terms. The FOIL method can be used to multiply two binomials
If X is a random variable representing the number of children that end up having light-colored eyes, then X follows a binomial distribution with success probability p = 0.25 and number of trials n = 5.
The variance of a binomial distribution with these parameters is n p (1 - p), so the variance in this case would be
5 • 0.25 • (1 - 0.25) = 0.9375 ≈ 0.9
