Answer:
17.3
Step-by-step explanation:
sin(30)=0.5
0.5*20=100
20*20+x*x=100
x=17.3
Answer:
the answer is to solve the equation like a good smart big wrinkle brain person instead of begging
Step-by-step explanation:
I believe the answer would be 19.625m squared. The formula for the area of a circle is 3.14 times the radius squared. Since the diameter is 5, the radius is 2.5 and 2.5 times 2.5 is 6.25. 6.25 multiplied by pi (3.14) is 19.625.
Answer:
I do believe that it is B.
Sorry I don't have much of an explanation.
With a given radius you can multiply by 2 and simply get the diameter. Getting the diameter of the circle would then allow you to use the equation pi(24.5). You can round pi to 3.14. 3.14*24.5=76.93. The circumference is 76.93.
