Answer:
7.06 x 10^(-7) ft 3
Step-by-step explanation:
We have the formula to calculate the volume of an octagonal Pyraamid as following:
<em>+) Volume of octagonal pyramid = 1/3 * Area of the base * Height</em>
As given, the base of the pyramid is an octagon with area equal to 15mm2
=> Area of the base = 15 mm2
The height of the pyramid is the length of the line segment which is perpendicular to the base - which is the red line.
=> Height = 4mm
So we have:
<em>Volume of octagonal pyramid = 1/3 * Area of the base * Height</em>
<em>= 1/3 * 15 * 4 = 20 mm3</em>
<em />
As: 1 mm3 = 3.53 x 10^(-8) ft 3
=> 20 mm3 = 7.06x10^(-7) ft 3
So the volume of the pyramid is : 7.06 x 10^(-7) ft 3
Answer:
<h2>The answer is 615 m²</h2>
Step-by-step explanation:
Area of a circle = πr²
where
r is the radius
From the question
r = 14 m
π = 3.14
The area of the circle is
A = 3.14 × ( 14 ) ²
= 3.14 × 196
= 615.44
We have the final answer as
<h3>615 m² to the nearest whole number</h3>
Hope this helps you
Answer:
11 is correct
12 should be 51°
Step-by-step explanation:
15/sin(104) = 12/sin(J)
J = 50.917°
It would be 18.75 because if you put it into a mixed number then multiply by 5 you get 18.75
