Answer:
LA = 20π square units
SA = 36π square units
V = 16π cubic units
Step-by-step explanation:
The value of the radius is needed before any area calculations can be done. It can be found from the Pythagorean theorem:
r² + 3² = 5²
r = √(25 -9) = 4
__
The lateral area is given by the formula ...
LA = πrs . . . . . where r is the radius and s is the slant height
LA = π(4)(5)
LA = 20π square units
__
The surface area is the sum of the lateral area and the base area. The latter is the area of a circle of radius 4.
SA = πr² + LA
SA = π(4²) +20π = 16π +20π
SA = 36π square units
__
The volume is given by the formula ...
V = 1/3πr²h
V = 1/3π(4²)(3) = 16π
The volume is 16π cubic units.

The formula for the volume of a cylinder is V=112h. The volume of a cylinder is three times the volume of a cone with the same radius and

if a×b=2a=b, evaluate 4×3 do not answer with a link,photo,file.
If you are comparing a*b=4*3, a = 4 and b = 3.
This would mean that 2a = 8.
If a×b=2a=b, evaluate 4×3 , Based on the given equation, the result of 4 × 3 is 12.
To evaluate 4 × 3 using the given information, we substitute the values of a and b into the equation.
An equation is a mathematical statement that shows the equality of two expressions or quantities. It consists of an equal sign (=) placed between the two sides of the equation. The expressions on each side of the equal sign are referred to as the left-hand side (LHS) and the right-hand side (RHS) of the equation.
Equations are used to represent relationships and solve for unknown values. They can involve variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. The goal is to find the value or values of the variable(s) that make the equation true.
Given: a × b = 2a = b
Let's assign a = 4 and b = 3:
4 × 3 = 2(4) = 3
Simplifying the equation:
12 = 8 = 3
Therefore, based on the given equation, the result of 4 × 3 is 12.

Answer:
x = 5 ln 1.2Step-by-step explanation:
[tex]5e^{0.2x}=6[/tex][tex]e^{0.2x}=6/5[/tex][tex]e^{0.2x}=1.2[/tex][tex]ln (e^{0.2x})= ln 1.2[/tex]0.2x = ln 1.2x = 5 ln 1.2Answer:
[tex] \displaystyle \rm {x}=5 \ln \bigg(\frac{6}{5} \bigg) \: or \: 0.91(approx)[/tex]
Step-by-step explanation:
we are given a logarithmic equation
[tex] \displaystyle {5e}^{0.2x} = 6[/tex]
we want to figure out x
remember that,
[tex] \ln( {e}^{x} ) = x[/tex]
therefore to use the above formula with our given equation
divide both sides by 5:
[tex] \displaystyle \frac{{5e}^{0.2x} }{5}= \frac{6}{5} [/tex]
[tex] \displaystyle {e}^{0.2x} = \frac{6}{5} [/tex]
take In both sides:
[tex] \displaystyle \ln({e}^{0.2x} )= \ln \bigg(\frac{6}{5} \bigg)[/tex]
by using the formula we acquire
[tex] \displaystyle 0.2x= \ln \bigg(\frac{6}{5} \bigg)[/tex]
we can rewrite left hand side as fraction
[tex] \displaystyle \frac{1}{5} x= \ln \bigg(\frac{6}{5} \bigg)[/tex]
multiply both sides by 5
[tex] \displaystyle x=5 \ln \bigg(\frac{6}{5} \bigg)[/tex]

Bob wants to invest his $3000 in an account that gets 3.4% interest rate compounded monthly, how much money will he have after 12 years? (round to nearest whole number)
Answer:
After 12 years Bob will have $ 4,508.80 in his account.
Step-by-step explanation:
Given that Bob wants to invest his $ 3000 in an account that gets 3.4% interest rate compounded monthly, to determine how much money will he have after 12 years the following calculation must be performed:
3000 x (1 + 0.034 / 12) ^ 12x12 = X
3000 x (1 + 0.0028333) ^ 144 = X
3000 x 1.0028333 ^ 144 = X
3000 x 1.502932 = X
4,508.80 = X
Therefore, after 12 years Bob will have $ 4,508.80 in his account.

What is a circle?A circle is a two-dimensional figure with a radius and circumference of 2pir.
The area of a circle is πr².
We have,
if a tangent and a chord are drawn from a point outside a circle, and the point of intersection of the tangent and the circle is labeled as point P, then the length of the tangent squared is equal to the product of the lengths of the two segments of the chord:
Now,
From the figure,
(2x - 9)² = 27 (2x + 2)
We can start by simplifying the left-hand side of the equation:
(2x - 9)² = 27 (2x + 2)
4x² - 36x + 81 = 54x + 54
Now we can move all the terms to one side and simplify:
4x² - 90x + 27 = 0
Next, we can use the quadratic formula to solve for x:
x = (-b ± √(b² - 4ac)) / 2a
where a = 4, b = -90, and c = 27.
Plugging in the values:
x = (-(-90) ± √((-90)² - 4(4)(27))) / 2(4)
x = (90 ± √(8100 - 432)) / 8
x = (90 ± √(7668)) / 8
x = (90 ± √(447)) / 8
x ≈ 11.16 or x ≈ 1.09
Rounding to a whole number.
x = 1
Therefore,
The value of x in the circle is 1.

Find the volume of the figure. Round to the hundredths place.
Answer:
i believe the answer is 142.42 in²
Step-by-step explanation:
what i did was 'separate' the cone and cylinder-
so the volume of cylinder formula is-
v=πr²h
and the volume for a cone is-
v=πr²h/3
now let us fill in the formulas with the information that we have-
v=π*2²*10=125.66
v=π*2²*4=16.76
now let us add the sums together-
125.66+16.76=142.42 in²
