Area of cylinder = curved area + 2 x base circle

Circles = 2 x π(8)² = 128π cm²

Curved area = circumference of circle x height of cylinder

Circumference of circle = 2πr = 2π(8) = 16π cm

Curved area = 16π x 4 = 64π cm²

Total surface area = 128π + 64π = 192π cm² = 603.19cm² (5sf)

Plzzzzzz help! What is the area of figure A?

zloy xaker [14]

Answer:

A=24m^2

Step-by-step explanation:

to find the area of this figure you can approach it multiple ways, the simplest way is to split it into two rectangles

respectively one 6m by 3m and another 3m by 2m

find the areas of each rectangle and add them both to get the total area of the figure

(6m*3m)+(3m*2m)=(18+6)m^2=24m^2
