Oh, dude, the radius of a circle is just half of the diameter, so for an 11-inch circle, the radius would be 5.5 inches. Like, it's just basic math, nothing to lose sleep over. So yeah, the radius is 5.5 inches, but who's really measuring, right?
A circle with a radius of 11 inches has an area of 380.13 square inches.
Twice its radius which is 11 inches
A cylinder that has a radius of 5 inches and a height of 11 inches has a surface area of 502.65 inches2
Half it and so 22/2 = a radius of 11 inches
The area is 1,520.53 inches2
A circle with a radius of 11 inches has an area of 380.13 square inches.
Twice its radius which is 11 inches
A cylinder that has a radius of 5 inches and a height of 11 inches has a surface area of 502.65 inches2
The radius of a circle with an area of 380 sq inches is 11 inches.
1,520.53 square inches.
Half it and so 22/2 = a radius of 11 inches
The area is 1,520.53 inches2
The surface area is 1,520.53 square inches.
The surface area is 1,520.53 square inches.
SA = 1,520.53 inches2
circumference = 2*pi*11 = 69.115 inches to 3 dp
