Manny uses a sprinkler system to water his lawn. Each lawn sprinkler sprays a distance of 9 feet in every direction. One lawn sprinkler is broken and is only spraying two thirds of the area it usually covers. How many square feet of the yard is being watered by the broken sprinkler? Leave the answer in terms of π.

6π square feet
12π square feet
27π square feet
54π square feet

Answers

Answer 1
54(pi) ft^2

9 is the radius
A = (pi)r^2

A = 81(pi)
81(pi) * 2/3 = 54(pi) ft^2
Answer 2
It would be the first one, A. 9 is the radius and you times it by 2/3 and you get 6

Answer:

C

Step-by-step explanation:

0.25 x 865

Answer:

Step-by-step explanation:

1,,,To determine which estimate has a lower percent error, we need to calculate the percent error for each estimate and compare them.

Percent error can be calculated using the formula:

percent error = [(actual value - estimated value) / actual value] x 100%

For the buttons estimate:

percent error = [(677 - 1000) / 1000] x 100% = -32.3%

For the large beads estimate:

percent error = [(22 - 50) / 50] x 100% = -56%

Since the percent error for the large beads estimate (-56%) is larger than the percent error for the buttons estimate (-32.3%), Elena's estimate about the buttons has less percent error.

To determine how much less, we can subtract the two percent errors:

percent error difference = (-56%) - (-32.3%) = -23.7%

Rounding to the nearest percent, Elena's estimate about the buttons has 24% less percent error than her estimate about the large beads.                              2,,,w weekly salary after a 25% raise, we can multiply his current weekly salary by 1.25 (which represents a 125% increase, since 100% + 25% = 125%). So, the correct answers are:

D. Multiply 865 by 1.25.

E. Add 865 and 1/4 of 865.

The steps for each option are:

A. Divide 865 by 0.25: This will not give Kevin's new salary after the raise. Instead, it will give the amount of the raise itself (since 25% of 865 is $216.25). To find the new salary, we need to add the raise amount to his original salary.

B. Divide 865 by 1.25: This will also not give Kevin's new salary after the raise. Instead, it will give his salary before the raise (since 865 ÷ 1.25 = 692, which is 100% of his original salary). To find the new salary, we need to multiply his original salary by 1.25.

C. Multiply 865 by 0.25: This will also give the amount of the raise itself (since 25% of 865 is $216.25). To find the new salary, we need to add the raise amount to his original salary.

D. Multiply 865 by 1.25: This will give Kevin's new weekly salary after the 25% raise.

E. Add 865 and 1/4 of 865: This is equivalent to multiplying 865 by 1.25, so it will also give Kevin's new weekly salary after the 25% raise.

F. Add 865 and 1 1/4 of 865: This is not a correct way to calculate Kevin's new weekly salary after the raise, since 1 1/4 of 865 is not a valid percentage increase.
