Answer:

59.73 cm²

Step-by-step explanation:

$2\pi r$

2 × π × 7

2 × 3.14 × 7

43.96 ÷ 4

10.99 cm²

11 cm - 7 cm = 4 cm

$2\pi r$

2 × π × 4

2 × 3.14 × 4

25.12 ÷ 4

6.28 cm²

10.99 cm² + 6.28 cm² = 17.27 cm²

7 cm × 11 cm = 77 cm²

77 cm² - 17.27 cm²

59.73 cm²

Solve the system of equations using elimination 2x+y=3 and 3x-y=12

Eddi Din [679]

2x + y = 3
3x - y = 12
Add both equations
5x = 15, x = 3
2(3) + y = 3
6 + y = 3, y = -3
Solution: x = 3, y = -3... or (3,-3)

Option A. is correct for the given condition.

Lets solve it through steps of range and functions,

First of all, Solve the equation:
$f(x) = |x|+5$
$= > x = -5$ (1)

$= > x = 5$ (2)

So these would be the ranges of X in between 5 and -5.

Hence option A. $R{f(x)eR [f(x) < 5}$ is correct.
