Hi there!

To solve, we can use right triangle trig.
We are given the value of ∠A, and side "x" is its adjacent side. We are also given its opposite side, so:
tan (A) = O / A
tan (33) = 25 / x
Solve:
x · tan(33) = 25
x = 38.49 ≈ 38.5
Answer:
Option A. 
Step-by-step explanation:
step 1
Find the volume of the sphere ( medicine ball)
The volume is equal to

we have
----> the radius is half the diameter
Convert inches to feet
Remember that
1 ft=12 in

assume

substitute


step 2
Find the weight of the ball
Multiply the volume in cubic foot by 100

Round to the nearest pound
