Answer:
SA = 4.91 in²
Step-by-step explanation:
A ball is a sphere, and the surface area of a sphere is
If our diameter is 1.25, the radius is half of that at r = .625
Filling in, we have
SA = 4(3.14)(.625)² and
SA = 4(3.14)(.390625) so
SA = 4.91 in²
Answer:
x = 10
Step-by-step explanation:
To find the value of x that will make the area of both figures to be equal, set the expression for the area of one figure equal to the other.
Thus:
(x + 5)×12 = x × 18
Solve for x
12x + 60 = 18x
Subtract 12x from each side
12x + 60 - 12x = 18x - 12x
60 = 6x
Divide both sides by 6
60/6 = 6x/6
10 = x
x = 10
Answer:
(-3,2)
Step-by-step explanation:
look at the dot called K, straight down you see -3 which is your X and if you look straight to the right of point K you see 2 which is your Y
(the whole bolded line that is horizontal is ur X and the whole bolded vertical line is ur Y)
Answer:
(9*X)-4=7 :)
