Answer:
120 square feet
Step-by-step explanation:
Area = length x width
Insert the two values. Width will represent height.
Area = 12 x 10
Solve.
Answer:
4x5 = 20
Step-by-step explanation:
Im not rlly sure at all but hope this helps :)
From the given description, we can come up with the equations:
x<y
IxI>y
We can find the two numbers by guessing and checking:
If we plug in -5 for x and 3 for y, it satisfies both equations.
30mx + my + 2nx +ny
———————————
15nx - 2my + nx -2ny
Answer:
A) 283500 ft³
B) 1057.26 π in³
Step-by-step explanation:
A) Volume of square based pyramid
= 1/3 × Area of the base × height
= 1/3 × (90 ft)² × 105 ft
= 283500 ft³
B) This figure is a composite figure
Step 1
Find the volume of the cone
=1/3 πr²h
r = radius = 8.5 in
h = height = 10 in
= 1/3 × π × (8.5 in)² × 10 in
= 240.83333333 π in³
≈ 240.83 π in³
Step 2
Find the volume of the cylinder
= πr²h
= r = radius = 8.5 in
h = height = 11.3 in
= π × (8.5 in)² × 11.3 in
= 816.425 π in³
≈ 816.43π in³
Volume of the figure = (240.83 π + 816.43 π) in³
= 1057.26 π in³
