Answer:
Step-by-step explanation:
Given
diameter of 41.6 m
So radius =41.6/2= 20.8
Solution
volume of a hemisphere=4/3πr^2
=4/3×3.14×20.8×20.8
=5433.9584/3
=1811.319
So the answer is 1811.319 =1811(nearest 10)
Answer:
y = 75
z = 43.3
Step-by-step explanation:
To find the value of y we use the trigonometric identity Sine.
Now to find the value of z we can use the trigonometric identity Tangent.
We know the value of y is 75 so it becomes,
Answer:
120 cm^3
Step-by-step explanation:
The surface areas are in the ratio 60 to 135 so the single dimensions are in the ratio √60 to √135.
Therefore the volumes are in the ratio (√60)^3 to (√135)^3 or 60^3/2 to 135^3/2.
So Volume of Pyramid B / Volume of Pyramid A
= 60^3/2 / 135^3/2.
Therefore we have the equation 60^3/2 / 135^3/2 = V / 405 where V is the volume of pyramid B.
V = (60^3/2 * 405) / 135^3/2
= 120 cm^3
