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

The function appears to be L(legos) = T(tower)^3

L = T^3

This checks out for t =1,2,3,4

The 100th tower would have 100^3 legos.

100^3 = 1,000,000.

The 100th tower would have 1 million cubes
