Answer:
2√3
Step-by-step explanation:
circle pass (h,k): (x-h)² + (y-k)² = r²
radius = √12 = 2√3
Answer:
1065
Step-by-step explanation:
A right square pyramid consist of
- 1 base area which is a square, area of square = l²
- 4 triangles, area of a triangle = 1/2 (slant height)(base)
area of 4 triangle = 2 (slant height)(base)
In question we are given perpendicular height of pyramid not the slant height so first we will calculate the slant height.
By using pythagorus:
Slant height = √(24²+8²)
= 8√10
Surface area = baseArea + 2 (slant height)(base)
= 16² + 2( 8√10)(16)
= 1065
