Step-by-step explanation:
For a estimate of pi we use 3.14. So 3.14x5x5x7=549.5
For a realistic answer its 549.778714378.....
Count all the squares to get the answer (the long ones that are connected are 10)

Answer:
Angle D is complementary to angle A
Step-by-step explanation:
Complementary angles sum to 90 degrees.
Since angle is B is 90 degrees, the sum of angles A and D are also 90 degrees to make a straight line with an angle measure of 180 degrees.
Answer:
Volume = length× width× height
v=lwh
v=8×6×7
v=48×7
v= 336inches
