Answer:
174cm^2
Step-by-step explanation:
Given data
L=9m
W=5m
H=3m
The formula for the total surface area of a cuboid is
SA=2lw+2lh+2hw
substitute
SA=2*9*5+2*9*3+2*3*5
SA= 90+54+30
SA= 174cm^2
Hence the surface area is 174cm^2
Answer:
239.34 ft²
Step-by-step explanation:
The lateral surface area of the entire cone is 188.40 ft² and the lateral surface area of the missing cone is 112.34 ft².
Therefore, the lateral surface area of the given stand cut from the right circular cone is (188.4 - 112.34) = 76.06 ft²
Hence, the total surface area of this given stand cut from the right circular cone = 76.06 + area of the two horizontal surfaces at top and at bottom.
= 76.06 + π × 4² + π × 6²
= 76.06 + 3.14(16 + 36)
= 76.06 + 163.28
= 239.34 ft² (Answer)
No it doesn't work for both therefore can't be a solution
Answer:
280 and 210
Step-by-step explanation:
For every 4 pages there has to be three more
Therefore we divide the number of pages total by 7
= 70
Geography = 70 * 4 = 280
Civics = 70 * 3 = 210
We add these together to check we have the correct number of pages
We know that the ratio is 4:3 as we multiplied those numbers with 70 respectively
Answer:
I believe it's x-5>30
Step-by-step explanation:
x-5>30
add 5 on both sides
x>35
