Given data

We are given that

Large lemonade= $6

Small lemonade= $4

He keeps 50% of the total

= 50/100*10

=0.5*10

= $5

Hence he will keep $5

Find r if 0=pi/6 rad sector 64m^2
kap26 [50]

Given:

Area of a sector = 64 m²

The central angle is \theta=\dfrac{\pi}{6}.

To find:

The radius or the value of r.

Solution:

Area of a sector is:

A=\dfrac{1}{2}r^2\theta

Where, r is the radius of the circle and \theta is the central angle of the sector in radian.

Putting A=64,\theta=\dfrac{\pi}{6}, we get

64=\dfrac{1}{2}r^2\times \dfrac{\pi}{6}

64=\dfrac{\pi}{12}r^2

64\times \dfrac{12}{\pi}=r^2

\dfrac{768}{\pi}=r^2

Taking square root on both sides, we get

\sqrt{\dfrac{768}{\pi}}=r

16\sqrt{\dfrac{3}{\pi}}=r

Therefore, the value of r is 16\sqrt{\dfrac{3}{\pi}} m.

Find the area of a floor that measures 12.75 ft. by 10.5 ft. 133.875 11.775 11.875 132.875
kompoz [17]
133.875
This is the answer because we are given the length and the width of this floor. We are assuming it is a regular rectangle.
So we just multiply the length and the width which is 12.74 x 10.5, which comes out to 133.875

Sally says it is possible to draw a triangle with these side length
professor190 [17]

Step-by-step explanation:

The longest side of a triangle cannot be longer than the sum of the two shorter sides. So if the 5cm and 12cm sides are the shorter sides, the third one cannot be longer than the 17cm. ... So 12cm is not longer than 5cm plus the length of the third side, and therefore the missing side cannot be shorter than 7cm.
