Step-by-step explanation:
cos F = HF/FG
cos 52° = x/(4.3)
0.6 = x/4.3
=> x = 4.3 × 0.6
x = 2.58
so the length of HF = 2.58 = 2.6 ft
Assuming that the balls are perfect sphere, then we can use the formula for the volume of the sphere to solve the volume of the ball. the volume of a spher is given by the formula:
V = (4/3) pi r^3
where pi = 3.1416
r is the radius
since D = 9 in
r = 4.5 in
V = ( 4/3 ) (3.1416) ( 4.5)^3
V = 381.7 cubic inches is the volume of one of the balls.
Answer:
Wat does that mean?
Step-by-step explanation:
Answer:
Step-by-step explanation:
A = πr²
Dividing by π
A/π = r²
Finding the square root of both side
√r² = √(A/π)
r = √(A/π)
Answer:
65
Step-by-step explanation:
Because 90+25 equals 115 and 115 minus 180 equals 65
