What is the approximate perimeter of a semicircle with a radius of 8 m?

use pi star times = 3.14.
express your final answer to the nearest hundredth.

answer:

  1,176

step-by-step explanation:

an exponent is a way to represent repeated multiplication. that is

  x² = x·x . . . . the exponent of 2 means x is a factor 2 times in the product

so, your expression means

  (14√6)² = (14·√6)·(14·√6)

of course, the commutative and associative properties of multiplication allow us to regroup these factors to some convenient order, such as

  (14·14)·(√6)(√6) = 196·(√6)(√6)

we know that multiplying a square root times itself gives the original number. (this is the whole point of a square root.) that is

  (√6)(√6) = 6

so, the product above is

  (14√6)² = 14·14·(√6)(√6) = 196·6 = 1,176

since there are no variables involved here, your calculator can give you this answer.

explanation:

the sine is the ratio of the opposite side to the hypotenuse. when the ange is acute (< 90°), the hypotenuse is longer than the opposite side of the right triangle, so the ratio of that side length to the hypotenuse must be less than 1.
