A bicycle tire has a diameter of 3 feet. How many turns of the wheel could it take for the bicycle to go 792 feet?

Andrew [12]

Answer:

84 complete turns

Step-by-step explanation:

In order to find the number of turns that the bicycle wheel is going to take while going 792 feet, we need to find the circumference of the wheel.

$C = \pi \: d = 3.14 \times 3 = 9.42 \: ft \\ no \: of \: turns = \frac{792}{9.42} \\ = 84.0764331 \\ = 84 \: turns$

Find the area of a sector with a central angle of 120° and a diameter of 7.3 cm. Round to the nearest tenth.

Andru [333]

Answer: $14cm^{2}$

Step-by-step explanation:

diameter=7.3cm

radius= $\frac{diameter}{2}$

= $\frac{7.3}{2}$

=3.65cm

angle =120°

area= $\frac{angle (tita)}{360}$ × $\frac{\pi r^{2} }{1}$

= $\frac{120}{360}$ × $\frac{22}{7}$ × $3.65^{2}$

= $13.95cm^{2}$

≅ $14cm^{2}$

to convert 67,000 inches into miles, which two ratios could you multiply by? algebra a. 12in\1 foot and 1mile\ 5280 feet b. 1 fo

Mrrafil [7]

Use these conversions:

1 foot = 12 in

1 mile = 5280 feet

67000 in * [1 ft /12 in] * [1 mile/5280 ft]

Then the answer is the option c.

7. Given a right triangle as shown below, use a calculator to estimate the length of the

Wewaii [24]

Answer:

D. 11.6 cm

Step-by-step explanation:

The missing length of the right angled triangle can be calculated using Pythagorean Theorem as shown below:

$c^2 - b^2 = a^2$

Where,

a = x cm

b = 11 cm

c = 16 cm

Thus:

$16^2 - 11^2 = x^2$

$256 - 121 = x^2$

$135 = x^2$

$\sqrt{135} = \sqrt{x^2}$

$\sqrt{135} = x$

$11.61895 = x$

$x = 11.6 cm$ (nearest tenth)
