1.4 Determine the area of the base of the tin in square meters You may us the formula: A = πr² Hint: radius = half of diameter π = 3,142 (3) 1.5 Determine the area of the curved cover of the tin in mm². Round off to the nearest 10 You may use the formula: A = L x H (3) Hint: The length of the cover is approximately equals to circumference of the base of the container. 1.6 Determine the volume of the tin in cubic meter. Hint: Volume of the tin is determined by multiplying the area of the base by the height of the tin. 1.7 What type of shape is the tin of Ricoffy? ​
