Question

Forestry

Forest service biologists roped off a circular area of recently burned forest to determine how well the forest was recovering: The circular sample area had a
32-foot radius and contained 220 new seedlings. Calculate the germination rate in seedlings per foot. Do not count a decimal as a seedling. A= ²

Answer 1

Given:

Radius of the circular sample area = 32 feet

Number of seedlings = 220

Step 1: Calculate the area of the circular sample area:

Area of a circle = π * (radius)^2

Area = π * (32)^2

Area ≈ 3.14 * 1024

Area ≈ 3216.96 square feet

Step 2: Calculate the germination rate in seedlings per foot:

Germination rate = Number of seedlings / Area

Germination rate = 220 / 3216.96

Germination rate ≈ 0.0683 seedlings per square foot

Therefore, the germination rate in seedlings per foot is approximately 0.0683.
