Answer:
254 cm²
Step-by-step explanation:
Calculate first the total area
A = 30*20 = 600 cm²
Then calculate the area of the cercle
A= 10.5²*π = 346.36≈346 cm²
Then substract the area of the circle from the total one:
600-346= 254 cm²
Yeah its gonna be 18 square feet in wide and length and the area is gonna be 36 square feet
Answer:
Minor arc BC - 130° (arc at which inscribed angle is subtended)
The major arc BC - 230°
Step-by-step explanation:
Angle BDC is inscribed angle subtended on the arc BC.
The measure of the angle BDC is 65°.
The Central Angle Theorem states that the central angle from two chosen points B and C on the circle is always twice the inscribed angle from those two points.
By the central angle theorem, the measure of central angle BOC (O is the center of the circle) has the measure of

Hence, the minor arc BC has the same measure as the central angle BOC that is 130°.
The major arc BC has the measure

The adjacent interior is 4
Answer:
65.94 cm²
Step-by-step explanation:
12.5/2 = 6.25 = radius of large circle
8.5/2 = 4.25 = radius of small circle
A= πr²
A of large circle = 3.14(6.25²) = 122.66
A of small circle = 3.14 (4.25²) = 56.72
122.66 - 56.72 = 65.94 cm²
