Given:

The expression is

To find:

The expressions which are equivalent to the given expression.

Solution:

We have,

In option A,

This expression is equivalent to the given expression.

In option B,

This expression is not equivalent to the given expression.

Option C,

This expression is not equivalent to the given expression.

Option D,

This expression is equivalent to the given expression.

Therefore, the correct options are A and D.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

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.
