Find the area and the circumference of a circle with diameter 8 ft. Use the value 3.14 for it, and do not round your answers. Be sure to include the correct units in your answers

a. Area of circle = 50.24 ft².

b. Circumference of circle = 25.12 ft.  

Step-by-step explanation:

Given the following data;

Diameter = 8ft

Pie, π = 3.14

Radius, r = diameter/2 = 8/2 = 4ft

a. To find the area of the circle;

Area of circle = πr²

Substituting into the equation, we have;

Area of circle = 3.14*(4)²

Area of circle = 3.14*16

Area of circle = 50.24 ft²

b. To find the circumference of the circle;

Circumference of a circle = 2πr

Substituting into the equation, we have;

Circumference of circle = 2*3.14*4

Circumference of circle = 25.12 ft.

the answer is 2/54

step-by-step explanation:

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
