Answer:

Step-by-step explanation:
Given that the figure is made up of portion of a square and a semicircle, we have;
BC ≅ AB = 6 cm
The area of semicircle BC with radius BC/2 = 3 is 1/2×π×r² = 1/2×π×3² = 4.5·π cm²
Triangle ABC = 1/2 × Area of square from which ABC is cut
The area of triangle ABC = 1/2×Base ×Height = 1/2×AB×BC = 1/2×6×6 = 18 cm²
The area of the figure = The area of semicircle BC + The area of triangle ABC
The area of the figure = 4.5·π cm² + 18 cm² =
.
g/2 + 4
last option is the answer
Answer:
2580 degrees rotated per second
Step-by-step explanation:
since you have to find the degrees it rotates per second.
you need to divide 430 by 60 to find rotations per second
1) 430/60
= 7.16666667 rotations per second
-then you have to multiply it by 360 degrees ,because their is 360 degrees in a circle
2) 7.16666667 (360)
= 2580 degrees rotated per second
<span>210 miles equals 1 and 1/2 inches (3 1/2"s or 0.5"). 1 and 1/2" is equal to two 3/4" (3/4 + 3/4 = 1 and 1/2). 1.5" is equal to 210 miles, and 1.5" is equal to 2 * .75", you can divide 210 miles by two, which gives you 105 miles.</span>
