The height of a semisphere is equal a radius of this hemisphere.
But... if we can talk about the height of the hemisphere ;)
R = 0.8m = 80cm then height of hemisphere is equal 0.8m = 80cm.
Answer: $22.50
Step-by-step explanation:
The interest will be gotten by using the formula:
= PRT
= Principal × Rate × Time
= 400 × 7.5% × 9/12
= 400 × 0.075 × 0.75
= $22.50
The interest is $22.50
