Consider the region bounded by
x2 + y2 = 64 with x ≥ 0, and y ≥ 0
. a solid is created so that the given region is its base and cross-sections perpendicular to the x-axis are squares. set up a riemann sum and then a definite integral needed to find the volume of the solid.

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
