The sprinkler in Rob's sprinkler system waters a circular area. The sprinkler is in an open part of Rob's lawn and waters up to 18 feet away. What is the area the sprinkler can water? Show your work. Use 3.14 for /pi and round to the nearest square foot.

Answers

Answer 1

Answer: What is the area the sprinkler can water?

Area = π r²

r = 18 feet

r² = r * r = 324

A = 3.14 * 324

A = 1017.36

A = 1017 square feet

Answer 2

Answer: a = 10.17 hope this helps

What is the name of the relationship between 1 and 4? Parallel Lines and Transversals A. corresponding angles B. alternate interior angles C. obtuse angles D. adjacent angles

Answers

The correct answer is B. alternate interior angles. Both angles are on the inside of the two parallel lines, making them interior angles, and they are alternate because they're not on the same sides of the transversal line (the line that cuts through the parallel lines). A is incorrect because corresponding angles are those that are in the same position on both parallel lines, C is incorrect because it's impossible to tell with the information given if the angles are obtuse, and D is incorrect because adjacent angles are those that are next to each other.

Answer:

The correct anwser is B hope this helps :)

Simplify the expression using the distributive property 9(4y-7)

Answers

The simplified expression using the distributive property is 36y - 63

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Using the distributive property, we can simplify the expression 9(4y - 7) as follows:

9(4y - 7) = 9 * 4y - 9 * 7

= 36y - 63

Hence , the simplified expression is 36y - 63

Angle a and angle b are complementary angles. The measure of ∠a is 42°. Which equation represents this situation with x representing the measure of ∠b ?

Answers

We know, sum of complementary angles are 90 degrees
So, a + b = 90 [ Equation ]

For solving: Just substitute the value of a = 42
42 + b = 90
b = 90 - 42
b = 48

Hope this helps!

Answer:

the answer would be 90 + 42 + = x
