pi x 15 x 15 = 225 x 22/7 = 707 & 1/7 sq ft.
Not clear which area you want. The surface area of the cylinder can only be determined if you give the length of the cylinder as well as its diameter. As you don't give this I conclude you want the area of the ends only. Each end will be the difference between the area of the 100 mm circle and the 30 mm circle. 100 mm diameter area = 7855 sq mm. 30 mm diameter area = 707 sq mm. Therefore area of end = 7148 sq mm, and you have two ends so total = 14296 sq mm

2 x radius squared assuming the corners of the square intersect the circle. the length of the sides of the square = (2r)sin45 so the area of the square = ((2r)sin45)e2 sin45 =~.707 (1/2 sq.rt. of 2), squared =0.5 so the equation becomes (2r)e2 x 0.5 or 4 x (r)e2 x 0.5 so 2 x radius squared = area of a square bound by a circle example: circle 3 inches radius bounds a square what is the area of the square 2 x 3 x 3 = 18 square inches length of the chords marking the sides of the square is ~4.2426 inches
Fairfield, California, including Cordelia, is in area code 707.
If you view the plane edge-on so that it appears as a line cutting through the sphere which appears as a circle, you can create a right triangle from the circle's center point down to the closest point on the line, then along the line to one of the points where it intersects the circle. The leg of the triangle going down from the center point is 8 meters long. The hypotenuse of the triangle, running from the circle's center to the point of intersection at the circles edge, is the radius of the circle which is 17 m. We can now calculate the remaining leg of this right triangle (side 1 squared + side 2 squared = hypotenuse squared) as 82+x2 = 172 so x = 15. This leg of the triangle is half the length of the line segment within the circle, or going back to 3 dimensions, it is the radius of the circle created by the plane passing through the sphere. The area of this circle is therefor pi * r2 where r = 15 so the area is approximately 707.

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.
