Answer:

1) A = π r² = 22/7 x 10² = 314.28 in²

2)A = π r² = 22/7 x 9² = 254.57 mm²

3) radius = 1/2 diameter

r = 1/2 x 3 = 1.5 in

A = π r² = 22/7 x 1.5² = 7.07 in²

4)A = π r² = 22/7 x 14² =616 cm²

5) radius = 1/2 diameter

r = 1/2 x 1.5 = 0.75 ft

A = π r² = 22/7 x 0.75² = 1.76 ft²

Step-by-step explanation:

<u>You cant mark anyone brainliest if you dont have 2 answers. so I am just copying and pasting so you can mark him brainliest and i dont have to give the wrong answer. lol</u>

Choose the most appropriate strategy and then use it to solve the quadratic equation.
dsp73

 (x-8) ^ 2 = 121
 
(x-8) = + / - root (121)
 x = 8 +/- root (121)
 The solutions are:
 
x1 = 8 + root (121)
 
x2 = 8 - root (121)
 2a ^ 2 = 8a-6
 2a ^ 2-8a + 6 = 0
 a ^ 2-4a + 3 = 0
 (a-1) (a-3) = 0
 The solutions are:
 
a1 = 1
 
a2 = 3
 x ^ 2 + 12x + 36 = 4
 x ^ 2 + 12x + 36-4 = 0
 x ^ 2 + 12x + 32 = 0
 (x + 4) (x + 8) = 0
 The solutions are:
 
x1 = -8
 
x2 = -4
 x ^ 2-x + 30 = 0
 
x = (- b +/- root (b ^ 2 - 4 * a * c)) / 2 * a
 x = (- (- 1) +/- root ((- 1) ^ 2 - 4 * (1) * (30))) / 2 * (1)
 x = (1 +/- root (1 - 120))) / 2
 x = (1 +/- root (-119))) / 2
 x = (1 +/- root (119) * i)) / 2
 The solutions are:
 
x1 = (1 + root (119) * i)) / 2
 
x2 = (1 - root (119) * i)) / 2

Step-by-step explanation:

You need to add them all up and then divide by the number of rates which is 5

1.700+650+680+710+695=3435

2.3435/5=687
