Answer:
3/4
Step-by-step explanation:
If you have a 1/4 chance of winning, the other team has a 3/4 chance of winning assuming the only options are to win or lose. If the other team wins, you lose, so you have a 3/4 chance of losing.

To find h, we gotta do reverse bedmas or pemdas !!
301.6= 3.14*h/3
first, we bring the 3 to the other side, to do that, we must perform the opposite operation. The 3 is being divided on this side, meaning we must multiply by 3 on both sides to get rid of it.
301.6 (3) =3.14*h (3) /3
904.8= 3.14 *h --------------(the 3's on this side are gone because they cancel each other out)
now since the 3.14 is being multiplied on this side, we must divide by 3.14 on both sides to get rid of it.
904.8/3.14 = 3.14*h /3.14
h= 208.2 !!
Answer:B
Step-by-step explanation:because it will give you more information and the more information you have the more likely you would get it correct.
You are told the circumference of the sphere. The circumference is the length of the circle around the widest part. You know the formula for the circumference of a circle in terms of radius, so you can find the radius of the sphere.
C = 2πr
496.12 yd = 2*3.14*r
(496.12 yd)/(2*3.14) = r = 79 yd
Then the surface area of a sphere is given by ...
A = 4πr^2
A = 4*3.14*(79 yd)²
A = 78,386.96 yd²
_____
You can also find the area of a sphere in terms of its circumference.
A = C²/π
A = (496.12 yd)²/3.14 = 78,386.96 yd² . . . . same as above.
(The surface area in your problem statement, 3117.25 yd², corresponds to a sphere with a circumference of about 98.94 yd. The circumference given in the problem statement is almost 5 times that, which is why the area is almost 5²=25 times the area in your problem statement. This is a good one to ask your teacher about.)
