WHOOPS i meant to say
is 78.5 squared the approxamite area of a circle with 31.4cm
is 78.5 squared the approxamite area of a circle with 31.4cm?
You have to tell us what 31.4cm represents.
Does it represent the radiu or diameter? Which one?
78.5 squared means to multiply 78.5 by itself.
78.5 x 78.5 = 6162.25
What does 6162.25 have to do with 31.4cm?
Please, clarify your question.
To find the approximate area of a circle, we can use the formula A = πr², where A represents the area, π represents pi (approximately 3.14159), and r is the radius of the circle.
Given that the radius of the circle is 31.4 cm, we can plug this value into the formula:
A = π(31.4 cm)²
To square 31.4 cm, we multiply it by itself:
A = π(31.4 cm) × (31.4 cm)
Calculating this expression gives us:
A = 984.51 cm²
Therefore, the approximate area of a circle with a radius of 31.4 cm is approximately 984.51 square centimeters.
