The radius of a circle is 7 centimeters
amm1812

a) So we know the formula of finding the circumference: 2*pi*R.

Assuming we make pi = 3.14:     2 * 3.14 * 7 = 43.96.

b) We also know the formula of finding the area: pi * r^2.

3.14 * 7^2. Using PEMDAS:

3.14 * 49 = 153.86

Find the value of the discriminant for all the equations. 1.5q2 +2q–3=0 2.3u2 -4u+1=0 3.7s2 +9s–4=0 4.6w2 –8w+5=0 5.5p2 +7p–3=0
kicyunya [14]

Answer:

Case 1: a = 1.5, b = 2, c = -3

D = 22

Case 2: a = 2.3, b = -4, c = 1

D = 6.8

Case 3: a = 3.7, b = 9, c = -4

D = 140.2

Case 4: a = 4.6, b = -8, c = 5

D = -28

Case 5: a = 5.5, b = 7, c = -3

D = 115

Case 6: a = 6.9, b = -5, c = 2

D = -30.2

Case 7: a = 7.2, b = 6, c = -4

D = 151.2

Case 8: a = 8.3, b = -3, c = 4

D = -123.8

Case 9: a = 9.9, b = 4, c = -7

D = 293.2

Case 10: a = 10.4, b = 8, c = -5

D = 272

Step-by-step explanation:

For all second order polynomial, the discriminant is equal to:

D = b^{2}-4\cdot a \cdot c

Case 1: a = 1.5, b = 2, c = -3

D = 22

Case 2: a = 2.3, b = -4, c = 1

D = 6.8

Case 3: a = 3.7, b = 9, c = -4

D = 140.2

Case 4: a = 4.6, b = -8, c = 5

D = -28

Case 5: a = 5.5, b = 7, c = -3

D = 115

Case 6: a = 6.9, b = -5, c = 2

D = -30.2

Case 7: a = 7.2, b = 6, c = -4

D = 151.2

Case 8: a = 8.3, b = -3, c = 4

D = -123.8

Case 9: a = 9.9, b = 4, c = -7

D = 293.2

Case 10: a = 10.4, b = 8, c = -5

D = 272

The square has a side length of 9.

The area of the full square would be 9^2 = 9 x 9 = 81 square cm.

The area of the triangle is 1/2 x 4 x 3 = 6 square cm.

The area of the shape = 81 -6 = 75 square cm.
