Solve S= lw + wh+ lh for h. Hint: Use the distributive property to factor out h.<br> the<br> vcloc
Ostrovityanka [42]

Answer:

{ \rm{S = lw + wh + lh}}

• Group the h terms by organised term arrangement :

{ \rm{S = (wh + lh) + lw}}

• Then using distributive property, factorise out the value h so that the reverse is true.

{ \rm{S = h(w + l) + lw}}

• for the variable "lw", divide it by h in order to add it to the bracket of (w + l). Make sure the reverse is true:

{ \rm{S = h(w + l) + h( \frac{lw}{h} )}} \\

• finally, completely factorise out the value h

\hookrightarrow \: \: { \boxed{ \boxed { \rm{ \:  \: S = h(w + l +  \frac{lw}{h} ) \:  \: }}}}

What is the lateral surface area of the cone?
hoa [83]

Answer:

135 pi centimeters squared

Step-by-step explanation:

Hello!

where la is lateral surface area

first \: the \: formula \: for \: the \: lateral \: surface \: are \: of \: cone \: is \\ la = \pi \times r \times l \\ where \: r = radius \\ l = slant \: height \\ therefore.first \: find \: the \: radius(r) =  \frac{d}{2}  \\ r =  \frac{18cm}{2}  = 9cm \\ so \: as \: we \: have \: the \: radius \: we \: can \: solve \: for \: the \: la \\ la = \pi \times r \times l \\ la = \pi \times (9cm) \times (15cm) \\ la = 135\pi \: cm {}^{2}
