Find the area of a circle with radius 14mm. Round your answer to the nearest tenth

Step-by-step explanation:

the formula for the area of a circle is multiplied by the radius square.

and so you would do pi multiplied by 14 squared which gives you 615.8 which is rounded.

=615.8mm

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

answer: it's d
