Answer:
954.56 in²
Step-by-step explanation:
A = 2×π·r² + 2·π·r·h
= 2×3.14×64 + 2×3.14×8·11
= 401.92 + 552.64
= 954.56 in²
It is 80 because if you do all the math it turns out to be 80
This is the concept of arithmetic, we are required to evaluate the given questions and simplify it to the appropriate number of decimals places. In Mathematics it is always appropriate that the number should be in 4 decimal place so that the error can be greatly reduced.
Thus;
16.83/15
=1.1220
The answer is:
1.1220
Answer:
(a)
Distance from player should be 13.82 feet or 36.2 feet
(b)
The ball will go over the net
Step-by-step explanation:
we are given
The ball follows a path given by the equation
where
x and y are measured in feet and the origin is on the court directly below where the player hits the ball
(a)
net height is 8 ft
so, we can set y=8
and then we can solve for x
we can use quadratic formula
So, distance from player should be 13.82 feet or 36.2 feet
(b)
we can plug x=30 and check whether y=8 ft
we know that
height of net is 8 ft
so, the ball will go over the net
B 24a-22=-4(1-6a) has no solution
