What is perimeter and area of this object?

Step-by-step explanation:

You have a circle with radius r = 3 ft and a 3-by-12 rectangle.

Area of circle = πr² = 9π ft²

Area of rectangle = 3 × 12 = 36 ft²

Total area = 36 + 9π ≈ 64.3 ft²

Perimeter of circle = 2πr = 6π ft

Perimeter of rectangular projections = 18 ft

Total perimeter = 6π +18 ≈ 36.8 ft

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
