The radius of a circle is 7 feet . What is the circle's area?

The circle's area is 153.93804 feet^2

Step-by-step explanation:

The formula for the area of a circle is

Using this formula, input the number 7 in for "r" and solve:

a = pi ( 7 )^2

a = pi ( 49 )

a = 153.93804 feet^2

The area of the circle is 153.93804 feet^2. Round the number to the specified decimal point.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
