Explanation	Answer
Problem	A tin of paint has a diameter of 9.5 cm. What is the area of the top of the tin?
Formula used	\$"Area" = \pi \times r^2\$
Step - 1	Given that, Diameter of the tin = 9.5 cm
Step - 2	Radius of top of tin = \$(9.5)/2 cm = 4.75 cm\$
Step - 3	Area of the tin = \$\pi \times r^2\$ ⇒ \$3.14 \times 4.75 \times 4.75\$ ⇒ \$70.84\$
Step - 4	Hence,the area of the tin is 70.84 cm.

Explanation

Answer

Problem

A tin of paint has a diameter of 9.5 cm. What is the area of the top of the tin?

Formula used

\$"Area" = \pi \times r^2\$

Step - 1

Given that,

Diameter of the tin = 9.5 cm

Step - 2

Radius of top of tin = \$(9.5)/2 cm = 4.75 cm\$

Step - 3

Area of the tin = \$\pi \times r^2\$

⇒ \$3.14 \times 4.75 \times 4.75\$

⇒ \$70.84\$

Step - 4

Hence,the area of the tin is 70.84 cm.
