The equation asks for radius, therefore, take half of 28 (diameter), which is 14.Substitute 14 right into the equation.C =2(pi)(14)C = 87.96 Your is C!


The equation sin (25 degree) amounts to StartFractivity 9 Over c EndFraction have the right to be provided to find the size of Line segment A B.

You are watching: Using the formula c = 2πr, find the circumference of a circle with diameter of 28 inches.

21.3 feet

Step-by-step explanation:

In the right triangle Δ ABC, the ∠ C = 90° and ∠ A = 25°.

Now, size of BC = 9 inches and length of the hypotenuse i.e. AB is c that we have to calculate.

Now, utilizing trigonometry we deserve to say that


feet ≈ 21.3 feet. (

Find the location of the square, which has a side length of 2.

Area of square = 2 x 2 = 4

Now multiply the location by the size b

Volume = 4 x 5 = 20 square systems full.
