Answer:
217.04 cm²
Step-by-step explanation:
We should first calculate the area of the rectangle:
A= 14*21 =294cm²
then we should substract the area of the half-cercle :
A'= (7²*π)/2=76.96 cm²
then the area of the shaded area is :
A"= 294-76.96= 217.04 cm²
Answer:
the answeis A 6+10
Step-by-step explanation:
Answer:
h=16/15 or 1 1/15
Step-by-step explanation:
4/5 +3/2h = 4/3 +h
-4/3 -4/3
4/5-4/3 +3/2h = h
-3/2h -3/2h
4/5-4/3 =h-3/2h
convert to same denominators (left side):
12/15-20/15 = h-3/2h
-8/15 = -5/2h
h=16/15
Scale factor:
10/4= 2.5
X = 5 x 2.5 = 12.5
Y= 8/ 2.5 = 3.2
Z= 15/2.5 = 5
