vladimir1956 [14]

Answer:

311 cm^{2}

Step-by-step explanation:

Taking a pizza to be a circle

Area of big pizza be x abd are of small pizza be y

hence difference = x-y

Area of a circle = \pi r^{2} where r is the radius

taking \pi to be 3.14

hence area x = 3.14 (\frac{36}{2} *\frac{36}{2}) = 1017.36

Area y = 3.14 (\frac{30}{2} * \frac{30}{2} )= 706.5

x-y = 1017.36- 706.5 =310.86 cm^{2}

310.86 cm^{2}

Dafna11 [192]

Answer:

Quadrant 2

Step-by-step explanation:

Sin = opp/hyp and opp is positive in quadrants 1 & 2.

Tan = opp/adj - we need one of these values to be positive and the other negative. adj is negative in quadrants 2 & 3.

Quadrant 2 is found in both of the scenarios that we need to occur.
