Find the area of the semicircle.

the diameter of the circle is 14

either enter an exact answer in terms of {pie} or use 3.14, for {pie} and enter your answer as a decimal.

76.93 units²

Step-by-step explanation:

Diameter, = 14

radius = 1/2 x diameter = 7

Area of circle = π r²

Area of semi-circle = 1/2 x area of circle = (1/2)π r²

given r = 7 and π = 3.14

Area if semicircle,

= (1/2)π r²

= (1/2)(3.14) (7)²

= 76.93 units²

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
