The diameter of circular garden is 18 feet. what is the approximate area of the garden?

A. 50 square feet

B. 100 square feet

C. 254.34 square feet

D. 803 square feet

Option C, 254.34 square feet

Step-by-step explanation:

Area of a circle formula:  A = πr^2

Step 1:  Find the radius

Since they give us the diameter, we need to find the radius.

18/2

9 = radius

Step 2:  Plug into the formula

A = π(9)^2

A = 81π

A = 254.34 square feet

 Option C, 254.34 square feet

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
