Volume and curved surface area of cone. please help i’ll give u brainlest

a). Volume of the cone = 301.6 cm³

b). Curved surface area of the cone = 188.5 cm²

Step-by-step explanation:

Formula for volume of the cone =

Where r = radius of the circular base of the cone

h = height of the cone

a). Volume of the given cone =

                                                = 96π

                                                = 301.59

                                                = 301.6 cm³

b). Curved surface area of the cone = πrl

    Here r = radius of the circular base

             l = lateral height of the cone

    Curved surface area of the cone = π(6)(10)

                                                           = 60π

                                                           = 188.49

                                                           ≈ 188.5 cm²

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
