Answer:
Step-by-step explanation:
A triangular pyramid has a base with an area of 21.8 square meters, and lateral faces with bases of 7.1 meters and heights of 9 meters. Enter an expression that can be used to find the surface area of the triangular pyramid.
The expression is written as:
Surface Area = Area of the base + 1/2( Perimeter × Slant height)
Answer: Two solutions
Step-by-step explanation:
1. x =(-2-√-76)/-8=(1+i√ 19 )/4= 0.2500-1.0897i
2. x =(-2+√-76)/-8=(1-i√ 19 )/4= 0.2500+1.0897i
The answer is 4
2•2•2=2x or 4
Answer:
its the first one I think
Step-by-step explanation:
Answer:
842.04 cm³
Step-by-step explanation:
Cylinder:
diameter = 6 cm
r = 6/2 = 3cm
h = 4 cm
Volume of cylinder = πr²h
= 3.14 * 3 * 3 * 4
= 113.04 cm³
Cube:
side = 9 cm
Volume of cube = side * side *side
= 9*9*9
= 729 cm³
Volume 0f composite figure = volume of cylinder + volume of cube
= 113.04 + 729
= 842.04 cm³
