The surface area of the exhibit is 1,638 cubic inches.
Step-by-step explanation:
Step 1:
If three prisms are out on top of each other we get a shape as follows;
The length of the base inches,
The width of the base inches, and
The height of the exhibit inches.
To find the surface area of the total exhibit we consider there to be only one shape which the above dimension.
Step 2:
There are 6 faces to the exhibit.
The surface area of a rectangular prism is given by;
By substituting the values, we get
The surface area of the exhibit is 1,638 cubic inches.
We first calculate the area of the entire pool and the side walk.
Given that the pool has a diameter of 60 feet and that the side walk surrounds the pool with a width of 5 feet. This means that the diameter of the entire pool and the side walk is 60 + 5 + 5 = 70 feet and the radius is 70 / 2 = 35 feet
Thus the area of the entire pool and the side walk is obtained as follows:
Given that the pool has a diameter of 60 feet, this means that the radius of the pool is 30 feet.
Thus the area of the pool is given by:
Therefore, the area of the sidewark is the area of the entire pool and side walk minus the area of the pool, this is given by:
Given that the pool has a diameter of 60 feet and that the side walk surrounds the pool with a width of 5 feet. This means that the diameter of the entire pool and the side walk is 60 + 5 + 5 = 70 feet and the radius is 70 / 2 = 35 feet
Thus the area of the entire pool and the side walk is obtained as follows:
Given that the pool has a diameter of 60 feet, this means that the radius of the pool is 30 feet.
Thus the area of the pool is given by:
Therefore, the area of the sidewark is the area of the entire pool and side walk minus the area of the pool, this is given by:
Answer:
x ≈ 65.4 °
Step-by-step explanation:
cos x =
Cos x =
Cos x = 0.4167
x = Cos⁻¹ (0.1467)
x ≈ 65.4 °
