4.67 would be a rounded answer. Really it's 4.666666666666666666 (the 6 go on forever) but we can't write that out.
Subtract 10 from both sides
A=55-10
=45
Point A is ( 2 1/4, 1 1/2)
Point B is ( -1 /4, 1 1/2)
Point C is ( 1/4, -2 1/2 )
I hope u get why this is why!
Enjoy the answers
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)
