Acurtain forest covers in area 5000 km^2. suppose that each year this area decreases by 6.5%. what will the area after 7 years?

3123.6 km^2 to the nearest tenth.

Step-by-step explanation:

This is exponential decay. Each year the area is  100 - 6.5 = 93.5% of the previous year.

Area after 7 years  = 5000(0.935)^7

= 3123.57 km^2.

i think c. but don't trust it.

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
