We know that
the Volume of the cone=(1/3)*B*h
B= area of the base
h= height of the pyramid------> 45 cm
then
B=pi*r²=pi*12²=452.16 cm²
V=(1/3)*[452.16*45]=6782.4 cm³
the answer is 6782.4 cm³
Answer:86%of 950= 817
Step-by-step explanation:
Area of triangle = (base x height)/2
There are all together 4 triangles and 1 square.
Therefore, surface area = area of square + 4 x area of triangle
height = 5.8 in, base = 6 in. area of square = 6x6 = 36 in^2.
area of 1 triangle = (5.8x6)/2
area of 4 triangles = 2x5.8x6 = 69.6 in^2
surface area = 69.6 + 36 = 105.6 in^2
