The surface area of a right square pyramid is given by A=b2+2bh where b is the length of a side of the base and h is the slant h

gizmo_the_mogwai [7]

Answer:

$h = \dfrac{A - 9}{6}$

Step-by-step explanation:

A=b^2+2bh

b = 3

The mean length of 10 childrens' big finger is 8.1cm.

sergiy2304 [10]

Answer:

The mean length of 10 children's big finger is 8.1 cm

Average length of all the 10 children's finger is (8.1×10) cm = 81 cm.

The mean length of 11 adult's big finger is 14.1 cm

Average length of all the 11 adult's big finger is (14.1×11) cm =155.1

Mean length of these 21 people's big finger is
$\frac{(81 + 155.1)}{21} = 11.242857$
Hence, <em><u>11.24</u></em> is the right answer.
