Answer:
28.75 cm^3 of space not used
Step-by-step explanation:
The volume of the box is
V = 4.5* 2.5 * 7 =78.75 cm^3
The gift takes up 50 cm^3
Subtract
78.75-50 = 28.75 cm^3
There is 28.75 cm^3 of space not used
Answer:
93 1/2 in^2.
Step-by-step explanation:
The Area = 8 1/2 * 11
= 17/ 2* 11
= 187/2
= 93 1/2 in^2.
Imagine that we cut the cone in half with a vertical plane. In this plane we'd see points a, b and c. We need to find the measure of angle bca, and then double that angle, to obtain the answer to this problem.
Note that tan (angle bca) = opp / adj = 2 / 6, or 1/3, or 0.333...
Working backwards to find angle bca, we use the inverse tangent function:
arctan 0.3333.. = approx. 0.322 radians, or 18.435 degrees.
Doubling that gives us the measurement of the angle formed between the line segments: 2(18.435 deg) = 36.9 degrees, approximately.
