Question

A rectangular piece of paper with length 35 cm and a width 18 cm has two semicircles cut out of it as shown below

Answer 1

Answer:

375.66 cm²

Step-by-step explanation:

The two semicircles add to a full circle.

For the circle, d = 18 cm.

r = d/2 = 9 cm.

A = LW - πr²

A = (35 cm)(18 cm) - 3.14(9 cm)²

A = 375.66 cm²
