Answer:
153.9 cm²
Step-by-step explanation:
Use the area of a circle formula to solve this question. Plug in the known value of the radius (7 cm) and use 3.1415 for the constant π(pi) in the equation.
[tex]\hrulefill[/tex]
[tex]\text{Area} = \pi r^2\text{~(plug in 7 for r)}\\\\\text{Area} = \pi (7)^2\\\\7^2 = 49\\\\\text{Area} = \pi \times 49\\\\\pi \approx 3.1415\\\\\text{Area} \approx 3.14153 \times 49\\\\\text{Area} \approx 153.9 \, \text{cm}^2\\\\= \boxed{153.9 \, \text{cm}^2}[/tex]
Therefore, the area of the circle is 153.9 cm².
