Answer:
Step-by-step explanation:
Use the formule V=4/3 *Pi*R^3
where R =10
so V=4/3*Pi*10^3
v= 4000Pi/3 =4188.7902
To find the answer we simply work out the equation.
cos (75) = 10/x
cos (75) * x = 10. Here, I simply multiplied both sides by x to move x to the left hand side of the equation.
x = 10 / cos (75) Here, I divided cos (75) on both sides to move cos (75) to the right hand side of the equation.
The cosine of 75 is 0.92175127, so, 10 / 0.92175127 = 10.8489137
B. they are directly proportional because she keeps taking 3 at a time to his 1 at a time.
The formula for the radius is
so the answer would be 6 inches
P^2 could also have -4 as an answer. Any time a number is squared, it is positive
