Answer:
2.5
Step-by-step explanation:
16-13.50
Since we know that the ratio of the model car to the real
car is 1:64, therefore we use this to solve this true length of the real NASCAR
vehicle, let us call this us X, so that:
1 : 64 = 3 inches : X
1 / 64 = 3 inches / X
X = 192 inches

The true length is 192 inches</span>
Answer:
Area = 7.853981 in^2 (2.5 Pi)
Perimeter = 11.42478 in (3.63Pi)
Step-by-step explanation:
Area
Lg semi circle area = Pi(2^2)(0.5) = 3.141593(4)0.5) = 6.283185 in^2
Sm semi circle area = Pi(1^2)(0.5) = 3.141593(2)(0.5) = 1.570796 in^2
added together = 7.853981 in^2
Perimeter
Lg semi circle perimeter = Pi(4)(0.5) + 2 = 8.283185 in
Sm semi circle perimeter = Pi(2)(0.5) = 3.141593 in
added together = 11.42478 in
Expression B cannot be simplified because it has no like terms
