314 divided by pi, 3.14
314/3.14 = 100
So the diameter is 100 feet.
100 divided by 2 = 50, which is the radius
pi times radius2 = area of circle
50 x 50 = 2,500
2,500 x 3.14 = 7,850 ft2
TA DA!!! 7,850 square feet!!!!!!!!!!!!!

Does a cylinder have a curved and flat surface?
Yes, a cylinder has both curved and flat surface. Considering a solid cylinder standing on its end, the circular base and the circular top are flat surfaces. The surface connecting the top and bottom is curved.
How do you calculate area of column?
Surface Area = (Circumference)(Height)* Volume = ∏r2 x Height *If you want to include the top and the bottom in the surface area of the column you have to add the area of the top and bottom. So, the Total Surface Area = [(Circumference)(Height)] + 4(∏)(Radius2)
How do you find the surface area of a cone?
A cone has two surfaces, lateral surface and its circular surface at the base.The surface area of a cone is the sum of the areas of these two surfaces, i.e. (1) area of the lateral surface and (2) area of its base.Let us consider a right circular cone to find its surface area.The lateral surface area of a right circular cone is π r lwhere,r is the radius of the circle at the bottom of the cone, andl is the lateral height of the coneThe surface area of the bottom circle of a cone is the same as for any circle, π r2Thus the total surface area of a right circular cone is: π r l + πr2 OR π r (l + r)
A solid shape with curved surfaces and two congruent circular bases?
A cylinder because there are two circular bases on the bottom and top and in the middle is a curved surface. hope I helped
What is the base of a cylinder called?
The base of a cylinder is called a circular base. It is a flat, circular surface that forms the top and bottom of the cylinder.
Brenda went to attach a string of beads along the circular bottom edge of the lamp shade shown below The diameter of the bottom of the lamp shape is 16 centimeters?
To go round the circumference of the shade, multiply 16 by 3.141592654 (the value of Pi) - you do the maths !
What is the surface area of a cylinder?
The surface area of a cylinder is 2πrh + 2πr². The variable r is the radius and h is the height.2πr² is the area of the top and bottom parts of the cylinder.2πrh is the area of the round circular part.
How many circular faces has a cylinder?
A (right circular) cylinder has 2 circular faces... one on top, and the other the bottom.
What is the base of a cone?
The circular bottom of the cone.
What is the 2d shape for a cone?
If you look down from the top, it is circular. From the bottom, it is circular. From the side, it is a triangle.
What is the surface area of a hemisphere?
picture a sphere. the surface area of a sphere is 4*pi*r^2.now, cut it in half. the surface area is 4*pi*r^2 / 2 =2*pi*r^2this is without including the bottom circular base
Do Lucky Bamboo plants ever grow thicker from the bottom or do they stay the same in circumference?
They stay the same circumference.
