The surface area of the sphere is approximately equal to 379.9 square centimetres.
Step-by-step explanation:
The surface are a of a sphere with respect to radius is 4πr². We're given the diameter, of 11 cm, so we know that the radius is 5.5 cm.
With that we can find the surface area:
[tex]a = 4\pi r^2\\a = 4\pi (5.5cm)^2\\a = 4\pi \times 30.25cm^2\\a = \pi \times 121cm^2\\a \approx 3.14 \times 121cm^2\\a \approx 379.9cm^2[/tex]

Brainliestis there is steps What is the solution to the equation log〖 (2x+4)〗=2 ? Round to the nearest hundredth, if necessary.
Answers
Answer:
x = 48
Step-by-step explanation:
log〖 (2x+4)〗=2
Raise each side to the base of 10
10 ^log〖 (2x+4)〗=10^2
The 10 ^log cancels
2x+4 = 100
Subtract 4 from each side
2x+4-4 = 100-4
2x = 96
Divide by 2
2x/2 = 96/2
x =48

6:22
12:44
30:110
Step-by-step explanation:
3 × 2 = 6, 11 × 2 = 22; put them together: 6:22
3 × 4 = 12, 11 × 4 = 44; put them together: 12:44
3 × 10 = 30, 11 × 10 = 110; put them together: 30:110

(3:11) x 2= 6:22
(3:11) x 3 = 9:33
(3:11) x 4 = 12:44
Here if you divide the ratios by the number you multiplied them with, it will give you 3:11.

Which equation represents a linear function that is proportional?
Answers
Answer:
A) f(x) = 1/3x
Step-by-step explanation:
You can rule out B and C-
B is a quadratic function, seeing as how x is being squared, and C is an absolute value function. Neither of these are linear so you don't have to worry about it here.
That leaves us with A and D, which are both linear.
Linear functions usually take the form of f(x) = mx + b. In a proportional linear function, b = 0.
So with that in mind, you should see that the b value for f(x) = 2x + 11 is 11, which should rule D out as well.
That leaves you with f(x) = 1/3x. As you can see, there's no b value in this function, which means b = 0 and the function is proportional.
Hope this helped :D
