What is the area of this figure?

Dima020 [189]

Answer:

$220.5 \: {yd}^{2}$

Step-by-step explanation:

Area of the figure = Area of the arc with radius 10 yd and central angle 90° + Area of rectangle with dimensions (10 + 5 - 3 = 12) 12 yd and (7 + 6 - 4 = 9) 9 yd + Area of square with dimension 4yd + Area of rectangle with dimensions 3 yd by 2 yd + Area of triangle with base 3 yd and height (5 + 3 = 8) 8 yd.

$= \frac{90 \degree}{360 \degree} \times 3.14 {(10)}^{2} + 12 \times 9 + {4}^{2} \\ + 3 \times 2 + \frac{1}{2} \times 3 \times 8 \\ \\ = \frac{1}{4} \times 314 + 108 + 16 + 6 + 12 \\ \\ = 78.5 + 142 \\ \\ = 220.5 \: {yd}^{2}$

Can someone help me out ??

Sloan [31]

Answer:

x = 3

LP = 3.5

Step-by-step explanation:

JK and LK are chords of the circle each of 7 units long.

Therefore,

JK = LK

Equal chords are equidistant from the center of the circle.

So,

PS = NS

4x - 6 = 6

4x = 6 + 6

4x = 12

x = 12/4

x = 3

LP = LK/2 ( Perpendicular dropped from the center of the circle to the chord bisects the chord)

LP = 7/2

LP = 3.5 units
