Use PEMDAS
1. 2(2^2)-2
=2(4)-2
=8-2
=6
2. 2((-2)^2)-(-2)
=2(4)+2
=8+2
=10
Answer:
C
Step-by-step explanation:
The circumference (C) of a circle = 2πr ← r is the radius
Given C = 15π the equating gives
2πr = 15π ( divide both sides by 2π )
r =
= 7.5 cm
The area (A) of a circle is calculated using the formula
A = πr² = π × 7.5² = 56.25π cm² → C
Answer:
24 yards
Step-by-step explanation:
your problem is area. area is lxh. the length is 8 and the height is 8. 6x3 is 24 yards

A dilation is when the figure is enlarged and a reduction is when the figure is reduced, smaller.
The scale factor for dilation is > 1 and reduction >0,<1
