3 : 4 : 5 = 3² : 4² : 5² = 9 : 16 : 25
The answer is B.
Hope this helps.
Answer:
volume of sphere;
Here r= 9ft
Let π =22/7
V = 4/3 π r^3
V = 4/3 (22/7) (9^3)
3054.85714 ft^3
Step-by-step explanation:
Answer:
1176.679ft²
Step-by-step explanation:
<u>The question is on surface area of a cylindrical fuel tank</u>
Equation for surface area of a cylinder
S.A = 2
rh +2
r²
where r is the radius of cylinder and h is height of cylinder
Diameter=7'⇒r=3.5' and h=50'
Surface Area= 2×3.142×3.5×50 + 2×3.142×3.5×3.5
S.A=1099.7+76.979=1176.679ft²
Answer:
Step-by-step explanation:
base length b = 3 in
slant height L = 3 in
base area = b² = 3² = 9 in²
lateral area = 4·½bL = 4·½·3·3 = 18 in²
surface area = base area + lateral area = 27 in²
Better yet, let y = 6 and solve for x.
6 = x^2 –2x + 5
Now solve for x.
