Is the measure of 21 equal to the measure of 22?
Why?
589
yes, because they intercept the same arc
no, because the sides of 22 are longer
no, because they intercept the circle at different
points

i am not sure :

step-by-step explanation:

a reflection across the x axis and a 90 degree rotation left and right.

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
