Answer:

r=\frac{15 }{2\pi }

Step-by-step explanation:

Circumference formula: 2πr

2πr=15

Divide 2π on both sides.

So since it won't be a integer you can leave it live that so your final answer will be:

r=\frac{15 }{2\pi }

Two sides of a right angle triangle is 5 inches each. how long is the third side
ser-zykov [4K]

Hello!

Tangent lines have only one point on the circle, meaning they form straight angles with the edge of the circle. The radius goes from the center of the circle to the point where the tangent line is on circle, creating a right angle.

Annette [7]

Answer:

1,824 \:  {in}^{2}

Step-by-step explanation:

Area of the figure = Area of rectangle with dimensions 48 in and 32 in + Area of triangle with base 48 in and height 12 in.

= 48 \times 32 +  \frac{1}{2}  \times 48 \times 12 \\  \\  = 1,536 + 24  \times 12 \\  \\  = 1,536 + 288 \\  \\  = 1,824 \:  {in}^{2}
