Answer:

The perimeter of the semi circle is gonna be π or 3.14

Step-by-step explanation:

So we know semi circle

The diameter is 2 so that basically also means the main circle diameter is also 2

we trying to find it’s circumference (perimeter)

We can follow the equation

C=πd

In this case d is 2

So 2π

And since that is full circle, half circle would be π

Step-by-step explanation:

Area of a trapezium = SOPS/2 × ph

Sops is the sum of 4+10 = 14

14/2 is 7. 7×4 = 28

A = 28cm²

Area = L×W

10×6= 60cm²

If p = -2 and q = 5, is the value of p/q equivalent to 2/5?

grandymaker [24]

Answer:

No.

Step-by-step explanation:

1. Subsutute p/q with the numbers given, p = -2 and q = 5.

-2 / 5.

2. Divide 2/5 and -2/5 and compare.

2 / 5 = 0.40

-2 / 5 = -0.40

-0.40 < 0.40

If they are not =, then they are NOT equivalent.

Which means, they are Not equivalent.
