Answer:

The central angle measure of the sector divided  by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector

Step-by-step explanation:

we know that

The formula to calculate the area of sector is equal to

A_s=\frac{x}{y}A_c

where

A_s ----> is the area of sector    

x ----> is the central angle measure of the sector in degrees

y  ---> total angle measure of a circle in degrees

A_c ---> represent the area of the circle

see the attached figure to better understand the problem

we have

x=m\angle ZYX=\theta^o ----> central angle of sector ZYX

y=360^o ----> total angle measure of a circle in degrees

A_c=\pi r^{2} ---> represent the area of the circle

substitute in the formula

A_s=\frac{\theta^o}{360^o} (\pi r^{2})

therefore

The central angle measure of the sector divided  by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector

Answer:

The formula T= 10d +20

A) what does each term on the right side of the equation represent?

  • 10d⇒ 10 degrees increase per 1 km and 20 deg surface temperature

B) Estimate the depth where the temperature is 60 degrees C.

  • 60=10d+20
  • 10d=40
  • d=4 km

C) What is the approximate temperature at a depth of 4km?

  • T=10*4+20
  • T=60 deg
