8^2 + 5^2 = 64+25 = 89 = square root 89
I don't have a calculator on me lol.
that specific side opposite the right angle is always the longest angle
a^2+b^2=c^2
Answer:
122.7792 sq. m
Step-by-step explanation:
diameter= 8.4 m
therefore, radius = r = 4.2 m.......( as radius is 1/2 of diameter)
height = h= 12 m
only the exterior is to painted so the total surface area of the cylinder is taken,
total surface area of cylinder = 2π r( h+r)
=2* 3.14* 4.2*(12+4.2)
=122.7792 sq. m
Answer:
Monomial; Standard form: 18a^2b^2
Step-by-step explanation:

Answer:
The area is approximately 453 ft²
Step-by-step explanation:
Area of a circle = 
If
= 22/7, and r = 12 ft
Area = (22/7)×12²
= 3.143*144
= 452.592 ft²
≈ 453 ft²
