Find the missing measure for a right circular cone given the following information. find r if t. a. = 12pi and l. a. = 8pi

r = 2 units

Step-by-step explanation:

Total area(T.A) of the circular cone is given by:

Lateral surface area(L.A) of the circular cone:

where

r is the radius and h is the height of the circular cone.

As per the statement:

and

then;

⇒

⇒

Divide both sides by we have;

or

⇒

r cannot be in negative

⇒ units

Therefore, radius of the circular cone is, r = 2 units

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
