Answer:
360mm^2
Step-by-step explanation:
Surface area of a square pyramid= Base area + Lateral area
Base area=10mm × 10mm
=100mm^2
Lateral area = (4) × (1/2) × (10) × √(12) ^ 2 + (5) ^ 2)
= 260 mm^2
Surface area= Base area + Lateral area
=100mm^2 + 260mm^2
= 360mm^2
Answer:
1) An triangle
2)Area is the same
3) Length times width then times 1/2
4)To find the polygon's area using the circle's measurement you us pi times radius squared(to find the circles area which is the same as the polygon's area)
HOPE THIS HELPS :)
4/30+3/100
first you need to find a common denominator. To do this, I normally just multiply the 1st fraction by the second denominator, and the 2nd fraction by the first denominator. Make sure to mulitply both the top and the bottom, so you don't accidentally shrink your value!!!
4/30*100/100=400/3000
3/100*30/30=90/3000
400/3000+90/3000=490/3000
you can simply by taking out a 10 from the final fraction to get 49/300, which I believe is the simpliest it can go.
Answer:
Options B, D and E
Step-by-step explanation:
From the picture attached,
AB and CE are the parallel lines and three lines AD, AC and BE are intersecting these parallel lines.
m∠A = m∠C = 90°
Therefore, AC is perpendicular to the lines AB, CD and CE.
Options B, D and E are the correct options.
