Area of a circle is (pi) x (radius)². So how do you want to approximate pi: We could choose 22/7, for example. So (15 in)² = 225 in², then multiply by 22/7 to get 4950/7 in², or 707 1/7 in².

What is the area of the semi circle 30 feet?
Is the 30ft the radius or the diameter. The area of a circle = Pi x (radius squared), so, if the diameter is 30ft, making the radius 15ft, the area would be Pi x(15 squared) square feet, and the area of its semicircle would be half of that, so the area required = Pi x (15 squared) divided by 2 = 353.429 sq ft On the other hand, if the diameter is 15ft, making the radius 7.5ft then the area required = Pi x (7.5 squared) sq ft for the full circle and half as much for the semicircle = 88.3573 sq ft As an extra; you will find that the area of the smaller semicircle is exactly one quarter of that of the larger semicircle, and I wonder if you can reason out why that is so.
What is the circumference of a 15 feet diameter circle?
47.14285714285714 radius = 1/2 of diameter radius=7.5 which is half of 15 using circumference of circle formula (2 * by pi * by radius) pi=22/7 2*22/7*7.5=47.14285714285714
What is the approximate area of a circle with a radius of 15 ft?
Approximate area of a 15 foot radius circle is a little more than 700 square feet.
Area of circle 15 cm radius?
The area of a circle with a radius of 15 cm is: 706.9 cm2
What is the area of a circle when the radius is 15?
Area of a circle= (22/7)*r^2 where, r is the radius of the circle when r=15, area of the circle= 3.14*15*15 = 706.5 sq.units
What is the equation to get the area of a circle if you have the radius?
The area of a circle is given by: pi multiplied by the square of the radius. So if the radius is 15, the area is 225pi (225 is 15 squared)

What is the area of a circle if the radius is 15 cm?
706.9 cm2
Area of a circle 15cm radius?
For a circle Area is defined as: A = π(r)2 Where "A" is the area, "r" is your radius and π = 3.14 So for your circle: A = 3.14 x (15)2
