A semi circle is half a full circle. Find the area of the full circle and divide it by 2.
Area of a circle = pi x r ^2
R is half the diameter
Area of full circle:
Area = 22/7 x 21^2
Area = 1386 sq. Ft
Area of stage = 1386/2 = 693 square feet
Both of your answers are correct. In the first equation, if you were to substitute 3 for x, because you have to do exponents first, you have 3^2, which is 9, and 9*6 =54. If you were to substitute -3 for x again you would have to do the exponents first which would be -3^2 which is 9, and 9*6 = 54.
For the second question, if I substitute 0.75 for t, I get -9 + 18 + 7. This is equal to 16, and therefore the answer would be D. Hope this helps! :D. Let me know if you have questions about my explanation, and feel free to post more questions.
Answer:
if the question is 'are the odds of him choosing a red favorable' then the answer would be 'yes' because he has a better than 50% chance; P(red) = 70%
Step-by-step explanation:
Distance sqrt of (x2-x1)/(y2-y1).
Distance = sqrt of 8/-7
Hope this helps!
Let me help you with that. Simply put, it is 4x+1.
It keeps the same slope, but just starts over to the left 2 from the original equation.
