Answer:

704π m^2

Step-by-step explanation:

Given data

radius r= 16m

Slant height l= 28m

Required

The surface area of the cone

The expression for the surface area is given as

T.S.A=πrl+πr^2

substitute

T.S.A=π*16*28+π*16^2

T.S.A=448π+256π

T.S.A=704π m^2

Hence the T.S.A is 704π m^2

Please simplify: −23d+81≤−98d+1

Strike441 [17]

$- 23 d + 81 \leq -98 d + 1$

Subtract 81 from both sides :

$-23 d + 81-81 \leq -98d+1 -81$

$-23d \leq -98d-80$

Add 98d to both sides:

$-23d +98 d \leq -98d-80+98d$

$75d \leq -80$

Divide both sides by 75 :

$\frac{75d}{75} \leq \frac{-80}{75}$

$d \leq =- \frac{16}{15}$

hope this helps!.
