This is the concept of areas of solid figures. The surface are of the solid figure formed when 2 square pyramids are attached will be given by:
SA=[number of triangular faces]*[Area of each triangle]
Number of triangular faces=8
Area of each triangle=1/2*bh
base=6/4=1.5 cm
height=2 cm
thus;
Area=1/2*2*1.5=1.5
The surface area will therefore be:
SA=1.5*8=12cm^2
The answer is
T=70/r=70/<span> 24/100=100*70/24=7000/24=291.6
</span>T=<span>291.6</span>
The formula for arc length is...
arc length = radius • central angle
Answer:
$300
Step-by-step explanation:
3/4 = 0.75
1200 * 0.75 = 900
1200 - 900 = 300
Best of Luck!
