What is the area of the drumhead on the drum shown below? Round to the nearest 10th.14 inches
Maurinko [17]
The formula for finding the area of a circle is

a = pi × radius^2

Since the diameter is 14 inches, the radius is 7 inches, so to solve...

a = pi × 7^2
a = 3.14 × 49
a = 153.86

Rounded to the nearest tenth...

Marysya12 [62]

Answer:

a) x > − 24 \frac{3}{4}

b) x < − 3

c) q < 56

Step-by-step explanation:

a) −2/5x−9<9/10

<=> 2/5x + 9 > − 9/10

<=> 2/5x > − 9/10 − 9

<=> 2×2/2×5x > − 9/10 − 9×10/10

<=> 4/10x > − 99/10

<=> x > − 99/4

<=> x > − 24 \frac{3}{4}

b) 4x+6<−6

<=> 4x < − 6 − 6

<=> 4x < − 12

<=> x < − 12/4

<=> x < − 3

c) q+12−2(q−22)>0

<=> q+12−2q −2×(−22)>0

<=> (q−2q) + (12+ 44) >0

<=> −q + 56 >0

<=> q < 56
