Answer:
1 pi: 3pi
Step-by-step explanation:
Step 1: Formula of surface area and volume of sphere
Surface area of sphere = 4 x pi x r^2
Volume of sphere = <u>4</u> x pi x r^3
3
Step 2: Apply values in the formula
r = radius
radius = diameter/2
r=18/2 = 9
S.A = 4 x pi x 9^2
S.A = 324pi
Volume = <u>4</u> x pi x 9^3
3
Volume = 972pi
Step 3 : Show in ratio
Surface area : Volume
324pi : 972pi
= 1 pi: 3pi

Answer:
b
Step-by-step explanation:
x = 2 in this situation, so plug in 2 for x.
f(2) = (x + 1)2
f(2) = (2 + 1)2
f(2) = (3)2
f(2) = 6
f(2) = 6. That means b is the answer.
Answer:
0
Step-by-step explanation:
We have two points we can use the slope formula
m = (y2-y1)/(x2-x1)
= (-4 - -4)/(9-4)
(-4+4)/(9-4)
0/5
=0
In parentheses 6 times 3 plus three times 2 minus 2 back parentheses plus new parentheses x times 3 minus 5 times 2 minus 3 equals 12.
there hope this helps!!
