Answer: Total Volume = 15π + 18 π= 33π cubic mm
Step-by-step explanation:
What is the volume of the composite figure? Leave the answer in terms of π.
_33π mm3
We have a cone here conjoined to a semi-sphere.
so
Cone volume: C = (1/3)*(πr^2) * h
semi-sphere volume : V = (1/2)* (4/3) * (π * r^3)
r = 3 mm and h = 5mm
so C = (1/3)*(π (3)^2) * 5 = 15π cubic mm
V = (1/2)* (4/3) * (π * 3^3) = 18 π cubic mm
Total Volume = 15π + 18 π= 33π cubic mm
Answer:
Equation: 
Step-by-step explanation:
By definition, the perimeter of a figure can be calculated by adding the lenghts of its sides.
Knowing this, you can write the following equation:
<em> [Equation 1]</em>
According to the data given in the exercise, the perimeter in feet of the fighter is:
Therefore, you can substitute this values into<em> [Equation 1]:</em>
Finally, you must solve for "x" in order to find its value. This is:
Answer:
67.5cm^2
Step-by-step explanation:
area of a triangle is 0.5xaxb
<span>I = Prt, where P is the principal, r is the annual </span>interest<span> rate in decimal form, and t is the loan period expressed in years.
</span>
First, Let us convert 3.4% into decimal form. <span>Move the decimal point two places to the left, adding in zeros as needed. 0.034</span>
Second, lets plug in our information.
250 * 0.034 * 3 = 25.50
Your simple interest is: $25.50
