Method: rumus luas lingkaran. Verified step-by-step solution with our free AI math solver.
Problem

A=πr2, r=10A = \pi r^2,\ r = 10

Step-by-step solution

  1. Terapkan A=πr2A = \pi r^2 dengan r=10r = 10.

  2. A=π⋅100=100π≈314.16A = \pi \cdot 100 = 100\pi \approx 314.16.

Answer

A=100π≈314.16A = 100\pi \approx 314.16
