pdf Circle Area - B
Tagged in 7.G, 7.G.B, 7.G.B.4, 7th grade, area, area of circles, circle area, circles, geometry, pi, radius
This worksheet provides structured practice finding the area of circles using a numerical approximation for pi. Students are given the radius of each circle and calculate area by applying the formula \(A=\pi r^2\), multiplying by \(3.14\), and rounding their final answers to the nearest tenth. A worked example models the process before students begin independent practice.
By focusing on circles with given radii, students build fluency with the circle area formula while strengthening decimal multiplication, rounding skills, and confidence working with geometric measurements.
This resource is ideal for introducing or reviewing the area of circles, reinforcing decimal computation, preparing students for assessments, or providing independent geometry practice.
