Given the radius is 6 inches, what is the area of the circle?
enyata [817]

Answer:

I wasn't sure how you're supposed to answer, so the answers for each scenario are in the explanation!

Step-by-step explanation:

A=\pi r^{2}

A=\pi (6^{2})

A=\pi (36)

From here, there can be a few different answers:

The exact answer is A=36π inches^2.

If you need to round, round this to wherever you need it: A=113.0973355292326... inches^2

If you're using 3.14 for pi, the answer is A=113.04 inches^2.

A set of scores with a normal distribution has a mean of 50 and a
dimaraw [331]
36, 43, 50, 57, 64

36 and 64 are two standard deviations out, so the empirical rule tells us 95% of scores will fall here with a normal distribution

How do you graph y= -5
olchik [2.2K]
Since y=k, there is a slope of zero, which is just a horizontal line k units from the x-axis.  In this case k=-5, so the graph of y=-5 is a horizontal line 5 units below the x-axis...

Convert r=53sinθ−cosθ to rectangular form.
Helga [31]

Answer:

y = \frac{1}{3} x + \frac{5}{3}

Step-by-step explanation:

r = 5/(3sinθ-cosθ)

multiply both sides by (3sinθ-cosθ):

r(3sinθ-cosθ) = 5

expand:

3rsinθ-rcosθ = 5

replace rsinθ with y and rcosθ with x:

3y-x = 5

add x to both sides:

3y = x + 5

divide both sides by 3:

y = 1/3x + 5/3

In Triangle A B C, what is the value of x? Triangle A B C. Angle A is 112 degrees. Exterior angle to angle B is 2 x degrees and
Stolb23 [73]

Answer:

70°

Step-by-step explanation:

∠A =112°,

Exterior angle to angle B is 2x, therefore ∠B = 180 -2x (angle on straight line)

Exterior angle to angle C is 2x + 12, therefore ∠C = 180 -(2x +12) (angle on straight line) = 180 - 12 -2x = 168 - 2x

∠A + ∠B + ∠C = 180 (sum o angles in a triangle)

112 + 180 - 2x + 168 - 2x = 180

460 - 4x = 180

4x = 460 - 180 = 280

x = 280/4 = 70

x = 70°
