Answer:
below
Step-by-step explanation:
hope it is well understood
2 = r(4)
To find r, you've gotta divide it out.
2/4 = r/4
1/2 or 0.5 = r
c=(0.5)t
This was kinda like Science
Answer:
85 cm²
Step-by-step explanation:
The base is a square with side length 5 cm. The area of this base is
A = s² = (5 cm)² = 25 cm².
If the slant height of each lateral face of the pyramid is 6 cm, then we can find the area of each such face using the area-of-a-triangle formula,
A = (1/2)(base)(height), which here is
A = (1/2)(5 cm)(6 cm) = 15 cm² per lateral side.
The total area of these sides is 4(15 cm²) = 60 cm².
Then the total surface area of the pyramid is A = 60 cm² + 25 cm² = 85 cm².
M 7=280. you just multiply 7 by 40 to get your answer. i am pretty sure.
