Question

function notation A circle has a radius of 26 cm. A second circle has an area that is 56 square cm more than the first circle. Represent the area of the second circle.

Answer 1

Answer:

Area of second circle = 56cm² + $\pi r^{2}$

Area of second circle = 2179.71cm²

Step-by-step explanation:

let the radius of the small circle be r and that of the big circle be R

Area small circle = $\pi r^{2}$

Area Big circle = $\pi R^{2}$

Area Big circle - Area small circle = 56cm²

$\pi R^{2}$-$\pi r^{2}$ =56cm²

The second circle is the bigger circle.

Area of second circle -$\pi r^{2}$ =56cm²

Area of second circle = 56cm² + $\pi r^{2}$

r =26cm

Area of second circle = 56cm² + $\pi r^{2}$

Area of second circle = 56cm² + $\pi* 26^{2}$

Area of second circle = 56cm² + $\pi* 26^{2}$

Area of second circle = 56cm² + 2123.71

Area of second circle = 2179.71cm²
