My answer:
The composite solid has two cones:
=> the volume of the big cone is:
V = (1/3)π·h = (1/3)*3.14*
*18 = 678.24 cubic meters
=> the volume of the small cone is:
V = (1/3)π·h = (1/3)*3.14*
*12 = 452.16 cubic meters
=> the volume of the composite solid :
= 678.24 + 452.16
=1130.4 cubic meters
Answer:
(B)The expression (5n)(9-p) is the product
(D)The expression 9-p has exactly two terms
Step-by-step explanation:
In the expression;
The coefficient of m is 1, therefore Option A is not true
The product of 5n and 9-p is (5n)(9-p), therefore Option B is true.
The expression 9-p has exactly two terms,9 and p.
Therefore, Options B and D are true.
