First is to understand the terms. Lateral area is the surface area of a 3D figure, excluding the area of any base. 
<span>Laterial Area (L.A.) of a right cone = pi*radius*slant height </span>
<span>radius = 1/2 * diameter </span>
<span>L.A. = pi*(1/2)*(4)*(15)=30*pi </span>

<span>the formula for this is pi*r*rt(r^2 + h^2). If the diameter is 4, then the radius is 2. If the slant height is 15, then to get the real height we use the Pythagorean Theorem and get rt(221). So the lateral area is pi*2*rt(2^2 + (rt221)^2)...= 2pi*rt(225) = 30pi = 94.248 meters squared which is rounded to 94 meters squared.</span>

Identify whether the series is a convergent or divergent geometric series and find the sum, if possible. A) This is a convergent
Darya [45]
A divergent series is a type of series in which the ratio is too large and the summation is held from one to infinity. Hence, the sum could not be found out. A convergent series, on the other hand, has a definite answer because one could be the ratio is small and the lower and upper limits are defined not equal to infinity either positive or negative.

Solve using the order of operations: 6.3 7 squared x 3.1
SVETLANKA909090 [29]
6.37² x 3.1

First is Exponents (6.37²):

40.6 x 3.1

Then, Multiplication:

40.6 x 3.1 = 125.9.

To remember the order of operations, the term PEMDAS can be used. (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.)
You do the equation in the order of the letters.

Example:

(5-2)5 + 2² / 6 -1 = ?

First, Parentheses:

(3)5 + 2² / 6 - 1

Then, Exponents:

(3)5 + 4 / 6 - 1

Then, Multiplication:

15 + 4 / 6 - 1

Then, Division:

15 + 0.7 - 1

Then, Addition:

15.7 - 1 

Then, Subtraction:

14.7

So that means, (5-2)5 + 2² / 6 -1 = 14.7
