Determine the angle at the centre of a circle with radius 12.0 cm for an arc length of of 21.0 cm.
nata0808 [166]

Answer:

\theta=\dfrac{7}{4}\ \text{radian}

Step-by-step explanation:

We have,

Radius of the circle is 12 cm

Arc length, l = 21 cm

It is required to find the central angle of the circle. The formula for the length of an arc of a circle is :

l=r\times \theta

\theta is central angle

\theta=\dfrac{l}{r}\\\\\theta=\dfrac{21}{12}\\\\\theta=\dfrac{7}{4}\ \text{radian}

So, the angle at the centre of the circle is \dfrac{7}{4}\ \text{radian}.

andriy [413]

Answer:

36

Step-by-step explanation:

Let's say Leslie starts with x oranges.

The first person buys 1/3 of the oranges, leaving behind 2/3 x.

The second person buys 4 oranges, leaving behind 2/3 x − 4.

The third person buys 1/4 of the remaining oranges, leaving behind:

3/4 (2/3 x − 4)

This amount equals 15. Solving for x:

15 = 3/4 (2/3 x − 4)

20 = 2/3 x − 4

24 = 2/3 x

36 = x
