What’s the surface area of a regular pyramid if the base is 7 and the height is 10
1 answer:
Answer:
Step-by-step explanation:
the base is a square, and then there are four triangles that meet at their tip.
so you need to find the area of the base, and the four triangles.
base-l*w=7*7=49
triangles=1/2*b*h*4=1/2*7*10*4=35*4=140
140+49=189

Answer:
50.24ft^3
Step-by-step explanation:
Volume of a cylinder
= Pi r^2 h
Given
pi = 3.14
Radius r = 2 ft and
Height h = 4 ft
Therefore
Volume = 3.14 x 2^2 x 4
= 3.14 x 2 x 2 x 4
= 50.24ft^3
