Answer:
X/2-7
Step-by-step explanation:
any number which is said to be less than another number let's say b should be subtracted from b.
Volume of cone formula: V = PI x r^2 x h/3
Volume of sphere formula: 4/3 x PI x r^3
Cone: 3.14 x 9^2 x 9/3 = 763.02 cubic inches
1/2 sphere: 1/2 x 4/3 x 3.14 x 9^3 = 1526.04 cubic inches.
Total volume : 1526.04 + 763.02 = 2289.1 cubic inches
All I know or all I understood was both 7 and 8 aren’t functions. Hope this helped
if your asking for the equation, it's t + 7 < 3
