* Example 6: A farmer grows his crops in a circular area of his land, He harvests his crops by driving his tractor in circles. The radius of his first circle is 10 m. The radius of each subsequent circle that he makes increases by 5m and he completes 50 circles to harvest his entire crop. a) What is the radius of his final circle. b) What is the area of the farmers land? Give your answer correct to the nearest square metre.

Step 1
The radius of the first circle is 10 meters. Each subsequent circle has a radius that increases by 5 meters. Therefore, the radius of the nth circle can be calculated using the formula: \[ R_n = R_1 + (n - 1) \times 5 \] where \( R_1 \) is the radius of the first Show more…
