Cutting speed, when applied to a grinding wheel, is called surface speed. What is the surface speed in ft/min of a 10-in-diameter grinding wheel revolving at 1,400 rpm? (Surface speed equals =circumference in feet times ×rpm.)

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.

we know that

major arc is defined as the bigger arc connecting two points on the edge of a circle. measure of major arc is always more than ° or π radian

in this problem

the mayor arc is bac

find the ratio of the measure of the major arc to the measure of the minor arc

therefore

the answer is the option

fo there supposed to be answer choices there
