What is the area of the circle if the diameter is 24cm?Round to the nearest hundredth.

452.16cm^2

Step-by-step explanation:

Area of a circle = pi r2

Given

Diameter = 24cm

Radius r = diameter/2

= 24/2 = 12cm

Pi = 3.14

Therefore

Area = 3.14 x 12^2

= 3.14 x 12 x 12

= 452.16 cm^2

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

f(x)=4
