The surface of a circle is given by the formula d2pi/4, so for our 44 inch diameter table, that gives 484pi square inches, which is aproximately 1520.531 square inches.
the area of a circle is pi times the radius squared. The diameter is 12, so the radius is 6 (half of the diameter). Therefore, the area is pi times 6 squared, which is 36 pi square centimeters. Also, if you want the answer in decimal, it's 113.09733552923255658465516179806 square centimeters.
By the diameter of the wire.

Area of the circle = pi*62 = 113.097 square feet to 3 decimal places
226.98 inches squared.

A circular shape with an area of 65 square feet has a diameter of 9.1 ft approx.
19.6 sq.ft
If the ratio of the lengths is a:b then the areas are in the ratio of the square of these, namely a2:b2The lengths are in the ratio 8:12 ⇒ 2:3Therefore the areas are in the ratio 22:32 ⇒ 4:9So the area of the larger table is 9/4 = 21/4 = 2.25 times the area of the smaller table.
Assuming the area in question in circular, area = pi*r*r where r, the radius is half the diameter. area = pi*7.5*7.5 = 176.7 square feet.
200.96 square feet.
Area of circular pan: pi*9 squared = 254.469 square inches Area of square pan: 18*18 = 324 square inches which has the greater area
Area: pi*2.6^2 = 21.237 square inches rounded
The area of a square with side x is x2 SQUARE units. A circle with diameter 1 unit, has an area of pi/4 square units. Since the area of a square with side of 1 unit is 1 square unit, let us call the area of a circle of diameter 1 unit to 1 circular unit. That gives 1 circular unit = pi/4 square units. So a square with sides of x units = x2 units = pi*x2/4 or pi*(x/2)2 units.
Area = pi*12.252 = 1847.453 square meters rounded to 3 dp
The shape of a pie is circular. If its diameter is d units, the area is 0.25*pi*d^2 square units.
