The circumference of the hub cap of a tire is centimeters. Find the area of this hub cap. Use 3.14 for π. Use pencil and paper.

dimaraw [331]

Answer:

Area of the hub = 470.42 cm² (Approx.)

Step-by-step explanation:

Missing information;

Circumference of the hub = 76.87 cm

Value of π = 3.14

Find:

Area of the hub

Computation:

Circumference of the hub = Circumference of circle

2πr = 76.87

2(3.14)r = 76.87

6.28r = 76.87

Radius of hub = 12.24 cm

Area of the hub = Area of circle

Area of the hub = πr²

Area of the hub = (3.14)(12.24)²

Area of the hub = (3.14)(149.8176)

Area of the hub = 470.42 cm² (Approx.)

Yes, If the circumference of the hub cap were smaller, Area will be small too.

26. A book costs sh. (x - 300) and a pen costs sh (x + 100). If Ndagire pad sh. 3300 for 3 books and 2 pens, how much did she pa

saul85 [17]

Answer:

500 and 900

Step-by-step explanation:

3(x - 300) + 2(x + 100) = 3300 ← distribute parenthesis

3x - 900 + 2x + 200 = 3300

5x - 700 = 3300 ( add 700 to both sides )

5x = 4000 ( divide both sides by 5 )

x = 800

Then

cost of book = x - 300 = 800 - 300 = 500

cost of pen = x + 100 = 800 + 100 = 900
