Answer:

19.54 m

Step-by-step explanation:

l(\widehat {AB})  =  \frac{ \theta}{360 \degree}  \times 2 \pi r \\  \\l(\widehat {AB})  =  \frac{140 \degree}{360 \degree}  \times 2 \times 3.14 \times 8 \\  \\ l(\widehat {AB})  =  \frac{7}{18}  \times 2 \times 3.14 \times 8 \\  \\ l(\widehat {AB})  =  \frac{351.68}{18}   \\  \\ l(\widehat {AB})  = 19.5377778 \\  \\ l(\widehat {AB})   \approx 19.54 \: m

Hunter-Best [27]

Answer:

a) 50.24 ft²

b) 150.72 ft²

Step-by-step explanation:

Jason is painting a large circle on one wall of his new apartment. The largest distance across the circle will be 8 feet.

The distance across a circle is also called a diameter, Hence,

D = Diameter = 8 ft

The Area of a circle = πr²

r = Diameter/2 = 8ft/2 = 4ft

π = 3.14

Hence,

The Area of the circle = π × (4 ft)²

= 50.24 ft²

a) Approximately the amount of wall the circle will cover is 50.24 ft².

b) How much area will he cover if he painted a circle on three walls?

This is calculated as:

1 wall = 50.24 ft²

3 walls = x

Cross Multiply

x = 3 × 50.24 ft²

x = 150.72 ft²
