bh=a or s2=a
multiply two sides
square one side
round
ex
one side=3.128
3.128X3.128=9.784384
3.1282= 9.784384
round that to 9.8
It is 61.9 square inches.
Radius is the square root of (71/pi) = 4.8 feet rounded to the nearest tenth
Entire surface area: (2*pi*49)+(14*pi*10) = 747.7 square feet
a square's sides are equal. so area = (length of side)2 = 33 inches so sqrt(33) = length of side length of side = 5.744....inches = 5.7 inches (to the nearest tenth of an inch)
Total surface area: (3.14*62)+(3.14*6*20) = 489.8 square units
The area of a circle to the nearest tenth if its radius is 4.5 is: 63.6 square units.
The answer depends on the units: nearest tenth WHAT? Square mile, square kilometre, square inch?
Its entire surface area works out as 747.7 square feet rounded to the nearest tenth
7.1 cm2
The area is 99.0 square units.
39.5%
5.7 inches
The answer is 0.4km2
It is 61.9 square inches.
Radius is the square root of (71/pi) = 4.8 feet rounded to the nearest tenth
47.1
Area of a square is the square of the length of any side.Length of any side is the square-root of the area = sqrt(13) = 3.60555 feet (rounded)Rounded to the nearest tenth, that's 3.6 feet.
