Answer: I think the correct answer is D.
Answer:
a. 9,416.9 mm²
Step-by-step explanation:
Given:
Circumference of a sphere = 172 mm
Required:
Surface area of the sphere rounded to nearest tenth
Solution:
First, we need to determine the radius of the sphere since we know the circumference.
Circumference = 2πr
Plug in the value of the circumference
172 = 2*π*r
Divide both sides by 2π
172/2π = r
86/π = r
r ≈ 86/π
Next, find the surface area of the sphere
Surface area = 4πr²
plug in the value of r
Surface area = 4*π*(86/π)²
= 4*π*86²/π²
= 4*7,396/π
= 9,416.87967
≈ 9,416.9 mm² (nearest tenth)
Answer:
7π/6.
Step-by-step explanation:
The range in the third quadrant is π to 3π/2 ( or π to 1.5π) so its not π/3 or 3π/4.
5π/3 = 1.67π so it's not this one.
7π/6 = 1.167π so it's this one.
Answer:
S=1/2INCH
V OF ONE BOX =L^3
=(1÷2)^3
=0.125
then
v of 24 cubes=v of one box × 24

Answer:
x=5
Step-by-step explanation:
Since both of these length are equal, 6x+4=8x-6, 2x=10, x=5
