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

                                 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

Michael draws three parallelograms. In each figure, he measures a pair of angles, as shown.
Phoenix [80]

we know that

In parallelogram, the sum of consecutive angles are 180

so, consecutive angles are supplementary

And opposite angles are equal

so, we will check verify each options

option-A:

Since, consecutive angles are supplementary

so, this is FALSE

option-B:

Since, only opposite angles are equal or congruent

so, this is FALSE

option-C:

Since, consecutive angles are supplementary

so, this is TRUE

option-D:

Since, consecutive angles are supplementary

so, this is FALSE
