Answer:
33 ft²
Step-by-step explanation:
The formula for the surface area of a square pyramid is:
SA = b² + 2bs
Where b is the measure of the base and s is the slant height
Let's substitute into this equation:
SA = b² + 2bs
SA = 3² + 2(3)(4)
Solve:
SA = 3² + 2(3)(4)
Square 3:
SA = 3² + 2(3)(4)
SA = 9 + 2(3)(4)
Multiply:
SA = 9 + 2(3)(4)
SA = 9 + (6)(4)
SA = 9 + 24
Add:
SA = 9 + 24
SA = 33
Therefore, the surface area is 33 square feet.

Answer:
24 yards
Step-by-step explanation:
The diameter of the circle is equal to 24 yards. The formula to find the circumference of a circle is pi*diameter, so you can work backwards to find your answer.
Answer:
Step-by-step explanation:
<u>Given equation:</u>
<u>Given variables:</u>
<u>Simplify, then solve:</u>
- x=2y-7
- = x = (2 * 5) - 7
- = x = 10 - 7
- = 3
- x = 3.
