What percent of 914 is 457

Answer:

Step-by-step explanation:

The formula for the surface area is A = 4πr².  This formula can be solved for r² and then the result solved for the radius, r:

         A

r² = --------     The radius of the sphere is as follows:

        4π

√(30 m²)

-------------- meters

     2√π

Answer:6 units C)

Step-by-step explanation:

Answer:

C.6

Step-by-step explanation:

The legs of an isosceles triangle are equal therefore you can put it this way:

-x+7=x+1

Then just solve for x

7-1=2x

X= 3

Finally put in the x value to the equation of the base

3(3)-3 = 6

The base is 6

Answer:3

Step-by-step explanation:

-9x+4=-8-5x

-4x+4=-8

-4x=-12

x=3

Answer:

Step-by-step explanation:

Add 5x so -9x+5x becomes -4x+4=-8 then subtract -4 and then -4+-8 becomes -12 and then solve for x which is -12/-4 which is 3.

Hence the missing angle is 115 degrees

Sum of angle in a pentagon

The sum of an interior angle of a pentagon is 540 degrees

Let the value of the fifth angle be "x", hence;

x + 85°+ 110° + 135° + 95° = 540

x = 540 - (85°+ 110° + 135° + 95°)

x = 540 - 425

x = 115 degrees

Hence the missing angle is 115 degrees
