The LATERAL Surface Area for the shape below is ____________. (assume the bases are the larger faces on the top and bottom.)

Zolol [24]

Answer:

$LA=210\ cm^2$

Step-by-step explanation:

we know that

The lateral area of the figure is given by

$LA=Ph$

where

P is the perimeter of the base (larger faces)

h is the height

Find the perimeter of the base P

$P=2(11+10)=42\ cm$

we have

$h=5\ cm$

substitute in the formula of lateral area

$LA=42(5)=210\ cm^2$

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).

Alla [95]

Area of shaded region is 18π square unit.

<u>Step-by-step explanation:</u>

Given :- A circle with center O and radius 9 cm

To Find :- area of shaded region that is area of ABC

Solution : - BC = 9 cm

∠ABC = 80° = Ф

so, area of sector = πr²Ф / 360°

= (π×9×9×80) /360°

= 18π square unit

hence, area of shaded region is 18π square unit
