Answer:

x = 11

Step-by-step explanation:

\frac{x + 2}{6}   -  \bigg( \frac{11 -x }{3}  -  \frac{1}{4}  \bigg) =  \frac{3x - 4}{12}  \\  \\ \frac{2(x + 2)}{2 \times 6}   -  \bigg( \frac{4(11 - x) - 1 \times 3}{3 \times 4}  \bigg) =  \frac{3x - 4}{12}  \\  \\ \frac{2x + 4}{12}   -  \bigg( \frac{4 4 - 4x- 3}{12}  \bigg) =  \frac{3x - 4}{12}  \\  \\ \frac{2x + 4}{12}   -  \bigg( \frac{41 - 4x}{12}  \bigg) =  \frac{3x - 4}{12}  \\  \\ \frac{2x + 4 - 41 + 4x}{ \cancel{12}}  =  \frac{3x - 4}{ \cancel{12}}  \\  \\ 6x - 37 = 3x - 4 \\  \\ 6x - 3x = 37 - 4 \\  \\ 3x = 33 \\  \\ x =  \frac{33}{3}  \\  \\ \huge \red{ \boxed{ x = 11}}

Please help me, I know it’s not the first one but I think it’s the last one. Can somebody please confirm or deny?
GaryK [48]

Answer:

B. 2.2π m² : 3.2π m²

Step-by-step explanation:

Given:

Slant height (l) = 2.2 m

Diameter (d) = 2 m

Radius (r) = ½(2) = 1 m

Required:

Lateral area and surface area

Solution:

✔️Formula for lateral area of a cone = πrl

Plug in the values

Lateral area of the cone = π*1*2.2

Lateral area = 2.2π m²

✔️ Formula for surface area of a cone = πr(l + r)

Plug in the values

Surface area of the cone = π*1(2.2 + 1)

Surface area = π(3.2)

Surface area = 3.2π m²

The answer would therefore be:

2.2π m² : 3.2π m²
