2cos theta = 1 -> cos theta = 1/2

Then theta = pi/3 + 2npi or -pi/3 + 2npi, where n is random interger

And the domain is restricted in [0,2pi]

So answer will be pi/3 or 5pi/3

Ksju [112]

Answer:

8 baskets worth 3 points each and 4 baskets worth 2 points each

Step-by-step explanation:

6 baskets worth 3 points each and 7 baskets worth 2 points each : wrong because 7 x 2 = 14.

10 baskets worth 3 points each and 1 basket worth 2 points : wrong because 1 x 2 = 2.

4 baskets worth 3 points each and 10 baskets worth 2 points each: wrong because 10 x 2 = 40.

A circular mirror has a diameter of 12 inches.what is the area, in square inches, of the mirror.
navik [9.2K]

Answer:  The area of the mirror is 113.14 sq. inches [approx.].

Step-by-step explanation:  Given that a circular can till 375 ft² of land in 15 min.

We are to find the area of the mirror in square inches.

The AREA of a circle with radius 'r' units is given by

A=\pi r^2.

The diameter of the circular mirror is 12 inches, so the radius of the mirror will be

r=\dfrac{12}{2}=6~\textup{inches}.

Therefore, the area of the circular mirror is

A=\pi r^2=\frac{22}{7}\times 6^2=\dfrac{22\times 36}{7}=113.14~\textup{sq inches}~\textup{[approx.]}

Thus, the area of the mirror is 113.14 sq. inches [approx.].
