What is the equation of the circle whose center and radius are given.

muminat

Hello!

The equation for a circle is

$(x - h)^{2} + ( y - k)^{2} = r^{2}$

(h,k) is the center
r is the radius

Put in the values you know

$(x - 7)^{2} + ( y + 3)^{2} = 7^{2}$

Simplify

$(x - 7)^{2} + ( y + 3)^{2} = 49$

The equation is $(x - 7)^{2} + ( y + 3)^{2} = 49$

Hope this helps!

Answer:

Step-by-step explanation:

Find the surface area:

Bottom base: 57 × 27 = 1,539

Top base: 21 × 27 = 567

Rectangular face: 23 × 27 = 621

Trapezoidal face: (21 + 57) ÷ 2 × 15 = 585

1,539 + 567 + 621 + 621 + 585 + 585 = 4,518

The surface area is 4,518 square inches
