a globe has a diameter of 24 inches. a smaller globe has a diameter of 18 inches. What is the surface are to volume ratio of the

faust18 [17]

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

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

Volume = 972pi

Step 3 : Show in ratio

Surface area : Volume

324pi : 972pi

= 1 pi: 3pi

Answer:

1 & 2 = Right Triangles

3 & 4 = Not Right Triangles

Step-by-step explanation:

Solved Using Pythagorean Theorem:

1) $9^{2} + 12^{2}$ = 225

$15^{2}$ = 225

2) $15^{2} + 36^{2}$ = 1521

$39^{2}$ = 1521

3) $10^{2} + 26^{2}$ = 776

$28^{2}$ = 784

4) $10^{2} + 12^{2}$ = 244

$16^{2}$ = 256
