Answer:
Step-by-step explanation:
Volume of a cube = (side)³
= (20)³
= 8000 cubic in.
Volume of the sphere which just fits in = 
Here, r = Radius of the sphere
Since, sphere just fits in, radius of the sphere = half of the dimension of the cube
r = 
r = 10 in
Therefore, volume of the sphere = 
= 4188.79 cubic inch
Volume of the space between the cube and sphere = 8000 - 4188.79
= 3811.21 cubic inch
We know that
l² = r² + h²
l² = (10.5)² + (36)²
l² = 110.25 + 1296
l² = 1406.5
l = √(1406.5)
l = 37.5 cm
Now,
CSA of cone = πrl
=> 22/7 × 10.5 × 37.5
=> 22 × 1.5 × 37.5
=> 1237.5 cm²
Area of 20 caps = 20 × 1237.5
=> 24750 cm²
Answer:
B. 60 degrees
Step-by-step explanation:
∠6 corresponds to ∠3, which is supplementary to ∠2.
∠6 = 180° -∠2 = 180° -120°
∠6 = 60°
Answer:
<h2>33k - 25</h2>
Step-by-step explanation:
-5(1 - 5k) - 4(2k + 5) <em>use distributive property a(b + c) = ab + ac</em>
= (-5)(1) + (-5)(-5k) + (-4)(2k) + (-4)(5)
= -5 + 25k - 8k - 20 <em>combine like terms</em>
= (25k - 8k) + (-5 - 20)
= 33k - 25
