Find the area and show work if you can.

Answer:

The area of figure is 420 000 ft².

Step-by-step explanation:

You can seperate the diagram into 2 parts, top is trapezium and bottom is rectangle. Then you have to use the formula for each part :

Trapezium,

$A = \frac{1}{2} \times (a + b) \times height$

Let a = 600 ft,

Let b = 900 ft,

Let height = 200 ft,

$A = \frac{1}{2} \times (600 + 900) \times 200$

$A = 150 \: 000 \: \: \: {feets}^{2}$

Rectangle,

$A = base \times height$

Let base = 900 ft,

Let height = 300 ft,

$A = 900 \times 300$

$A = 270 \: 000 \: \: \: {feets}^{2}$

Lastly, you have add both areas together :

$A = 150000 + 270000$

$A = 420 \: 000 \: \: \: {feets}^{2}$

The volume of a sphere is 80pi cm3. What its is surface area to the nearest whole number

vlabodo [156]

Volume = (4/3) * PI * radius^3
80 * PI = (4/3) * PI * radius^3
The 'PI's' cancel out leaving
80 = (4/3) * radius^3
radius^3 = 80/(4/3)
radius^3 = 60

radius = cube root (60)
