Question

Bart designed a logo using circles of different sizes. The diameters of three of the circles are

shown. Which measurement is closest to the area of the largest circle in square centimeters?

A 20.7 cm2

B 136.8 cm2

C 34.2 cm2

D 65.1 cm

Answer 1

B 136.8 cm²

Explanation:

Add the diameters of the three smaller circles to find the diameter of the largest circle.

D = 3 cm + 2.5 cm + 1.1 cm = 6.6 cm

area = πr²

area = 3.14 × (6.6 cm)²

area = 136.8 cm²
