Answer:
Step-by-step explanation:
Area of any triangle could be always calculated as base length multiplied by the height perpendicular to the aforementioned base divided by 2. Therefore:
A = 18 * 11 / 2 = 198 / 2 = 99
Answer:
multiplication.
Step-by-step explanation:
A good way to remember the order of operations is Please Excuse My Dear Aunt Sally, or PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. If multiplication and division are in the same problem, you go in order. Same with addition in subtraction. What that means in this example is that since in PEMDAS, the M is first, you would multiply first instead of subtracting. :)
area = pi x r^2
circumference = 2x pi x r or pi x d
1st one diameter = 9.5 cm
so radius = 9.5/2 = 4.75
area = 3.14 x 4.75^2 = 70.85 square cm
circumference = 3.14 x 9.5 = 29.83 cm
2nd one radius = 4
area = 3.14 x 4^2 = 50.25 square cm
circumference = 2 x 3.14 x 4 = 25.12 cm
It’s $11 you just divide 55 by 5 to get that.
