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.
The area of South Carolina is approximately 32,020.2 square miles when rounded to the nearest tenth.
39.5%
5.7 inches
The answer is 0.4km2
