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

natita [175]

Answer:

D. - 1/6

Step-by-step explanation:

M + 2/3 = 1/2

M = 1/2 - 2/3

\frac{1}{2} - \frac{2}{3} = \frac{3}{6} -  \frac{4}{6} = -\frac{1}{6}

What’s the answer for a, and b, and how would you solve it?
xxTIMURxx [149]

Answer:

a) negative

b) -7/6

Step-by-step explanation:

The x value increased, but the y value decreased so the line goes down and has a negative slope

(y₁-y₂)/(x₁-x₂) is the slope where (x₁,y₁) and (x₂,y₂) are points on the line

(4-(-3))/(-1-5)=7/-6
