Q. The diameter of s circle is 4 find the area to the nearest tenth
Question Prompt: Question prompt: What is the area of a circle with a diameter of 4, rounded to the nearest tenth?
Identify Formula: Identify the formula for the area of a circle.The formula for the area of a circle is A=πr2, where A is the area and r is the radius of the circle.
Calculate Radius: Calculate the radius of the circle.The radius is half of the diameter. Since the diameter is 4, the radius r is 24=2.
Substitute Radius: Substitute the radius into the area formula.A=π(2)2
Calculate Area: Calculate the area using the value of π as approximately 3.14159.A=3.14159×(2)2A=3.14159×4A=12.56636
Round Area: Round the area to the nearest tenth.The area of the circle, rounded to the nearest tenth, is approximately 12.6.
