It's option À because half the diameter to turn into radius which is 14. Then substitute the height and radius to the the volume formula of a right cone: Pi x radius^3 x height then divide it by 3. Then u should get 2411.69 in^3
Answer:
y = 1 , x = 3
Step-by-step explanation:
3x + y = 10
x = 2y + 1
3(2y + 1) + y = 10
6y + 3 + y = 10
7y = 7
y = 1
x = 2(1) + 1
x = 3
Let n = one of the angles
Let 2n -30 = the other
n+ 2n -30 =90⁰ (because they are complementary)
Combine like terms -- 3n -30 = 90
Add 30 to both sides of the equation
3n=120°
Divide both sides by 3 and n=40° 2n -30 = 80 -30 = 50°
So one angle is 40° and the other is 50° and those angles are complementary.
Answer: The volume of pyramid is 6720 ft³
Step-by-step explanation:
Given: Base edge of a square pyramid = 24 feet
Slant height = 37 feet
Therefore height of pyramid is given by
where h is height, l is slant height and b is base edge of pyramid
So we have
Height of pyramid is 35 feet
Now the volume of a pyramid is given by
where V is volume , b is base edge and h is height of pyramid
Therefore
Hence , the volume of pyramid is 6720 ft³
