The picture in the attached figure
we know that
surface area=2*area of the base+perimeter*height
area of the base=area of the triangle
area of the base=3*4/2----> 6 cm²
perimeter of the base=perimeter of triangle
perimeter=3+4+5----> 12 cm
height=x cm
surface area=2*6+12*x
surface area=204 cm²
12+12*x=204
12*x=204-12
12*x=192
x=192/12
x=16 cm
the answer is16 cm
Answer:
52° 86' 65"
Step-by-step explanation:
20° + 30° + 2° = 52°
15' + 41' + 30' = 86'
18" + 32" + 15" = 65"
In the dimension of the frisbee given to be 10.2 inches in diameter, there are three significant figures. All, from 1, 0 and 2. Since these values are all significant, the last digit determines the greatest possible error allowed that is only in the tenths digit. The circumference of the frisbee is calculated through the equation,
C = πD
Substituting,
C = π(10.2 in) ≈ 32.0 in
Answer: 10.11 gallons
Step-by-step explanation: So I took the 8 gallons + 8liters. I figured you can’t do that. So i took the 8 Liters and converted it into gallons. And i got 2.11 gallons. So i did the math and added 2.11 + 8 gallons. The result was 10.11 gallons. Hope that will work
