Question 1.Correct Answer:384 m²
Solution:The lateral area of the prism = Perimeter of the base x Height
The bases are the sides with dimension 5 x 7 . So the perimeter of the base will be equal to 2(5+7) = 24 m
Thus, the lateral area of prism = 24 x 16 = 384 m²
Question 2:Correct Ans:7.5 mm
Solution:The slant height is the hypotenuse of the Right Angled Triangle which is formed by the half of the base length and the height. Base length of given prism is 9mm. So half of the base length will be 4.5mm. Height of pyramid is 6mm. Using Pythagorean Theorem, we get:
Slant Height =
Therefore, the slant height of the pyramid will be 7.5mm
Answer:
no its not a perfect cube, we need to multiply a seven to make it perfect cube
Step-by-step explanation:
answer from GAUTHMATH
You can solve this problem and calculate the arc lenght, by applying the following formula:
s=θr
s: it is the arc lenght.
θ: it is the central angle (θ=2π/3).
r: it is the radius of the circle (r=10 inches).
When you substitute these values into the formula, you obtain the arc lenght (s):
s=θr
s=(2π/3)(10)
Then, you have that the value of the arc lenght is:
s=20.94 inches
Answer:
The dot is the center
the long line is the diameter
the circle is the circumference
the half way line is the radius
