Answer:

78.5 cm^2.

Step-by-step explanation:

The diameter d = 10 so the radius = 1/2 * 10 = 5cm.

Therefore the area = π r^2

= π * 5^2

= 3.14 * 25

= 78.5 cm^2.

QUICKLY!!!<br> I need the answer to this, please

Yuri [45]

8/(1/6) = (8/1)/(1/6) = (8/1) * (6/1) = 48/1 = 48

Patel found the quotient incorrectly since he got 1/48.

To check the division, he needed to multiply 48 by 1/6 and get 8.

Instead, he multiplied 1/48 by 6, so the multiplication done as a check is also incorrect.
