Answer:
Lateral area of a regular pyramid with square is 12.64 square unit
Step-by-step explanation:
Given : A regular pyramid with base is a square.
We have to find the lateral area for the regular pyramid.
Lateral area of a regular pyramid with square =
Where, a is side of square
and h is height of pyramid.
Substitute, a = 2
and h = 3
we have,
Lateral area of a regular pyramid with square =
Simplify, we have,
Lateral area of a regular pyramid with square = 12.64
Thus, The Lateral area of a regular pyramid with square is 12.64 square unit

The total amount is $ 1015.82 and interest amount is $ 165.82
<em><u>Solution:</u></em>
<em><u>The formula for amount when interest is compounded annually is:</u></em>
Where,
"A" is the total amount
"P" is the principal
"r" is the rate of interest in decimal form
"n" is the number of years
<em><u>From given, $850 at 2% for 9 years, compounded annually</u></em>
P = 850
t = 9 years
<em><u>Substituting the given values we get,</u></em>
Thus total amount is $ 1015.82
Interest amount = Total amount - principal
Interest amount = 1015.82 - 850
Interest amount = 165.82
Thus total amount earned is $ 1015.82 and interest amount is $ 165.82
Answer:
Radius: 8
Circumference: 50.27
πr^2 = Area of circle
201.06 = πr^2
divide by pi
201.06 / π = 63.9993857161 = 64
64 = r^2
Square root both sides to get radius.
= 8
r = 8
Circumference = π x diameter
Diameter = 2 x radius
Circumference = π x 16 = 50.2654824574 = 50.27
