How To Calculate The Area Of Circle In Terms Of Pi пђ Owlcati Determine the area of a circle with a radius of 7 m. give your answer in terms of pi. all you need to do is substitute 7 for r in a = π * r². a = π * r². a = π * 7². a = π * (7 * 7) a = π * 49. a = 49π. the final answer is 49π m2 (put the number before pi and express your answer in terms of the relevant units squared). The formula to calculate the area of a circle using radius is as follows: area of a circle = π × r 2. and, to calculate the area of a circle using diameter use the following equation: area of a circle = π × (d 2) 2. where: π is approximately equal to 3.14. it doesn't matter whether you want to find the area of a circle using diameter or.

Pi In Area Of A Circle Problem: find the area of a circle with a radius of 5 units. solution: plug in 5 for r in the formula a = πr 2 and solve. a = π5 2. a = 25π (follow the order of operations and square 5 before multiplying it by pi.) a = (25) (3.14) a = 78.5. answer: the area of a circle with a radius of 5 units is 78.5 square units. For example, if the radius is 5 inches, then using the first area formula calculate π x 5 2 = 3.14159 x 25 = 78.54 sq in. task 2: find the area of a circle given its diameter is 12 cm. apply the second equation to get π x (12 2) 2 = 3.14159 x 36 = 113.1 cm 2 (square centimeters). That means we can get the area of the circle by finding the area of the triangle. now, the base of the triangle would be equal in length to the outer most strip. or equal to the circumference of the circle. and the height would be equal to the radius. using the formula for the area of a triangle, we have –. How to calculate the area. the area of a circle is: π ( pi) times the radius squared: a = π r2. or, when you know the diameter: a = (π 4) × d2. or, when you know the circumference: a = c2 4π. example: what is the area of a circle with radius of 3 m ?.

In that case, these would be the steps to follow: use the formulas to calculate the circumference and area: c = 2πr and a = πr². the circumference should equal c = 2π × 8 cm = 50.265 cm. the area should equal a = π × (8 cm)² = 201.06 cm². to check your results, input the 8 cm radius in the calculator. The area of a circle is all the space inside a circle's circumference. in diagram 1, the area of the circle is indicated by the blue color. the area is not actually part of the circle. remember a circle is just a locus of points. the area is enclosed inside that locus of points.
