Find the lateral area of a regular pentagonal pyramid that has a slant height of 14 in. and a base side length of 6 in . a) 20 in.2 b)240 in.2 c)42 in.2 d) 420 in.2

The lateral area of a regular pentagonal pyramid is given by formula =

where 'P' is the perimeter and 'l' is the slant height.

Perimeter of regular pentagonal pyramid = base side

=

= 30

Slant height(l) = 14 in (Given)

Substituting the value in the formula, we get

Lateral area =

= 210

Hence, the lateral area of the regular pentagonal pyramid is 210 .

Here, the first option should be 210 instead of 20.

Therefore, Option 1 is correct answer with lateral area as 210 square inches.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
