Answer:
..........
Step-by-step explanation:
i don't understand 25 2 ??
7/2= radius (3.5)
V=πr2^<span>h
V=</span><span>π3.52*12
V= 461.81 </span>
The formula for circumference is C= 2(pi)(r)^2. Because diameter is double the radius, and the diameter is 8 ft, the radius is 4 ft. So, plug that into the equation, and you get: C=2(pi)(4)^2. The answer is 32 pi ft. If the question asks for the exact answer, keep the pi as it is, but if it says to round, multiply 32 by pi and round.
Answer: volume of the cube is (7 cm)^3= 343 cm^3
Given:
The matrix equation is:
To find:
The value of matrix C.
Solution:
Let 
. Then the given equation can be rewritten as
On substituting the values of the matrices, we get
Therefore, the correct option is C.
