Answer:

The area of the quarter circle is 16\pi\ cm^{2}

Step-by-step explanation:

we know that

The area of a quarter circle is equal to

A=\frac{1}{4}\pi r^{2}

we have

r=8\ cm

substitute the value

A=\frac{1}{4}\pi (8)^{2}

A=16\pi\ cm^{2}

In ΔSTU, the measure of ∠U=90°, SU = 7, UT = 24, and TS = 25. What ratio represents the tangent of ∠T?
Vinvika [58]

Answer:

Tan T = 7/24

Step-by-step explanation:

Firstly, please check attachment to have a picture of the triangle we are solving.

Now, we are concerned with calculating the ratio that represents the tangent of angle T.

Mathematically, the tangent of an angle is the ratio of the length of the opposite to the length of the adjacent.

In this question, our opposite is 7 while the adjacent is 24.

Thus Tan T = 7/24

prohojiy [21]

Answer:

113.04 cm³

Step-by-step explanation:

diameter = 6cm

so radius = 3cm

Volume of sphere = \frac{4}3}\pi r^3

= 4 * 3.14 * 3 * 3 *3 / 3

=  4 * 28.26

= 113.04 cm³

Possible number of learners in the
Anestetic [448]

Find multiples of 30 and 40:

30: 30, 60, 90, 120, 150

40: 40, 80, 120, 160

The least common multiple is 120, so every 120 minutes they willl both ring.

1 hour = 60 minutes:

120/60 = 2 hours.

The bells ring together every 2 hours.

8 + 2  = 10 am

10 +  = 12pm

12 + 2 = 2 pm

The bells will ring together at am, 12 pm and 2 pm.
