Rectangle WXYZ with height h and width w is rotated 360° about segment WY. Which choice gives the solid formed and its surface area?

Rectangle, A = 2 • w • h square units
Rectangle, A = w • h square units
Cylinder, A = 2π • w • h + 2π • w2 square units
Cylinder, A = π • w • h + π • w2 square units

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms

no this is a nonlinear negative

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
