Answer:

Perimeter b = circumference b = 10π; Area b = 50π

Perimeter c = circumference c = 10.5π; Area b = 27π

Step-by-step explanation:

b. Circumference = perimeter

Circumference of semicircle= πr=10π =Perimeter

Area of semi circle=πr^2/2=10^2π/2=50π

c. Circumference = 7/4πr=1.75*6π=10.5π=Perimeter

Area of the diagram = 3/4πr^2=0.75π*6^2=0.75π*36=27π

450 g in 2:13

<u>Total proportion asked for </u>=2+13=15

<u>Now comparing g with ratio, or whatever </u>
