Circle A has a radius of 9.0 cm. The shortest distance between B and C on the circle is 8.5 cm. What is the approximate area of

love history [14]

Answer:

38.25 cm²

Step-by-step explanation:

We use the formula for the length of an arc to find the central angle of the sector of the circle.

Then we use the formula for the area of a sector of a circle to find the area.

Length of arc of circle of radius r:

$s = \dfrac{n}{360^\circ}2 \pi r$

s = arc length

n = measure of the central angle of the sector

$s = \dfrac{n}{360^\circ}2 \pi r$

$8.5~cm = \dfrac{n}{360^\circ}2 \pi \times 9.0~cm$

$n = 54.1^\circ$

Area of sector of circle of radius r:

$A = \dfrac{n}{360^\circ} \pi r^2$

A = area of sector of circle

n = measure of the central angle of the sector

$A = \dfrac{54.1^\circ}{360^\circ} \pi (9.0~cm)^2$

$A= 38.25~cm^2$

Write the equation of the line which passes through (1, 2) and with slope of −1/3

Sati [7]

Answer:

Step-by-step explanation:

The equation of a line which passes through <em>(x₁, y₁)</em> and with slope of <em>m</em> in point-slope form:

y - y₁ = m(x - x₁)

m = -¹/₃

(1, 2) ⇒ x₁ = 1, y₁ = 2

Therefore, the equation of the line which passes through (1, 2) and with slope of −1/3 in point-slope form:

y - 2 = -¹/₃(x - 1)

y - 2 = -¹/₃x + ¹/₃ {add ¹/₃x to both sides}

¹/₃x + y - 2 = ¹/₃ {add 2 to both sides}

¹/₃x + y = 2¹/₃ {multiply both sides by 3}

x + 3y = 7
