In the circle the measure of angle QPR in radians is π/4.

What is a circle?

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the centre.

The length of the arc QR is 4π, which is 1/2 of the circumference of the circle P.

Therefore, the circumference of the circle is -

2πr = 2π(8) = 16π

The angle subtended by the arc QR at the center of the circle is therefore -

θ = arc length / radius

θ = (4π) / 8

θ = π/2

Now, consider the triangle QPR.

The angle QPR at the center of the circle is equal to twice the angle subtended by the arc QR at any point on the circumference of the circle.

Therefore -

2∠QPR = θ = π/2

Solving for ∠QPR, we get -

∠QPR = (π/2) / 2

∠QPR = π/4

Therefore, the measure QPR is π/4.

∠ACB

Step-by-step explanation:

- ∠ACB

∠ACB is the only angle out of the three given that doesn't directly touch side AB, so this must be our answer

Answer:

C

Step-by-step explanation:

pythagorean theorem: a²+b² = c²

area of square = length²

c = side opposite right angle = length of square Z

thus, area of square Z = c²

area of square X = a² (or b², it doesn't matter)

area of square Y = b² (or a²)

a² + b² = c²

region x + region y = region z

[tex]f(x) = x^3 -6x^2 -11x +k \\\\\text{If (x +3) is a factor of f(x), then,}~ f(-3) = 0\\\\~~~~~~~f(-3) = 0\\\\\implies(-3)^3-6(-3)^2 -11(-3) +k = 0\\ \\\implies -27-54+33 +k=0\\\\\implies -48+k = 0\\\\\implies k = 48[/tex]

Answer:

The formula for volume of a cone is area of a circle times height, divided by 3.

Therefore volume is pi times radius squared times height, divided by 3.

V = (3.14)(14)^2 (14)/3

V = (3.14) (196)(14)/3

V = (3.14) (2744)/3

V = 8616.16/3

V = 2872.05333

Answer:

r = 4/5

Step-by-step explanation:

Formula

Sum of an infinite geometric series = a / (1 - r)

Givens

Sum = 5*a

a = a

r = ?

Solution

5a = a/(1 - r)                   Divide both sides by a

5a/a = a / (a * (1 - r)       The a's on the right cancel

5 = 1 / (1 - r)                    Multiply both sides by 1 - r

5*(1 - r) = 1*(1 - r)/(1 - r)   The 1 - r s on the right cancel

5*(1 - r) = 1                     Remove the brackets.

5 - 5r = 1                        Subtract 5 from both sides

5-5 - 5r = 1 - 5               Combine

-5r = - 4                          Divide by - 5

r = 4/5

Four times the quotient of 3 divide by 4

We know that we are going to be multiplying 4 by something because in the statement we have four times.  Reading further we also know that we are going to be dividing 4 from 3 which means that we will have 3/4.  Finally, we see that we multiply our 3/4 by 4 which gives us our final solution.
