Answer: 63 ft^2
Step-by-step explanation:
the formula for the area of a circle is A = π r ^2. the radius (r) is 1/2 of the diameter.
first, we'll plug in the radius of table #1 into the equation (A = π 4 ^2) and get an answer of 50.27 ft^2. then plug in radius of table #2 (A = π 6 ^2) and get 113.1 ft^2. now find the difference of the areas by subtracting (113.1 - 50.27) to get an answer of 62.83 ft^2. which will round up to 63 ft^2.
Answer:
Secant
Step-by-step explanation:
Tangents are ongoing lines that occur on the outside of a circle.
A secant is an ongoing line that passes through a part of the circle that does not pass through the center.
A chord is a line of definite length that is entirely within the circle, stretching from one side to the other, but does not go through the center point of the circle.

Answer:
Step-by-step explanation:
<u>Perimeter is:</u>
- P = 40 cm
- and
- P = 2x - 4 + 5x - 13 + x + 9 = 8x - 8
<u>Comparing the value:</u>
- 8x - 8 = 40
- 8x = 48
- x = 8 cm
<u>Are formula:</u>
<u>Replacing values:</u>
- A = 1/2(x + 9)(2x - 4)
- A = 1/2(8 + 9)(2*8 - 4) = 1/2*17*12 = 102 cm²
