5 0

Answer:

15.14 cm^2

Step-by-step explanation:

Area of rectangle = 4cm x 3 cm = 12cm^2

Radius of the circle = 2 cm

Area of 1/4 of a circle = (pi x r^2) / 4

= (3.14 x 4) / 4 = 3.14 cm^2

3.14 cm^2 + 12cm^2 = 15.14 cm^2

vesna_86 [32]

Answer:

10

Step-by-step explanation:

\frac{2(10)^2(10-5)}{10(10)}

Square the 10.

\frac{2(100)(10-5)}{10(10)}

Subtract 10 with 5.

\frac{2(100)(5)}{10(10)}

Multiply the numbers in the numerator.

\frac{2(500)}{100}

\frac{1000}{100}

Divide 1000 with 100.

=10
