Detremine the surface area to the nearest inch, Mathematics

Assignment Help:

If a tabletop has a diameter of 42 in, Detremine the surface area to the nearest inch? (π = 3.14)

a. 1,384 in2

b. 1,319 in2

c. 1,385 in2

d. 5,539 in2

c. The area of a circle is πr2. The diameter  = 42 in, radius = 42 ÷ 2 = 21 in, so (3.14)(21)2 = 1,384.74 in2. Rounding to the nearest inch, the answer is 1,385 in2. If you select a, you rounded the ?nal answer incorrectly.  If you select d, you used the diameter rather than the radius.
