Step-by-step explanation:
To calculate the diameter of a circle, multiply the radius by 2. If you don't have the radius, divide the circumference of the circle by π to get the diameter. If you don't have the radius or the circumference, divide the area of the circle by π and then find that number's square root to get the radius. To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.Write down the formula for finding the circumference of a circle using the diameter. The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.

48? i guess. i hope this helps u out with ur question
ILL GIVE 20 POINTA
What do you need help with no picture?
parenthesis, exponents, multiplication, division, addition, subtraction.
(14)/(7)(5)(-3)^2 solve exponent first and then the multiplication part (7x5)
(14)/(35)(9) 14 divided by 35 is .4
(.4)(9)=3.6 .4 multiplied by 9 is 3.6 <- that's the answer for 7
remember parenthesis first so we will do 6-1 first which is 5. after parenthesis, well do exponents. 5^2 is 25.
we will finish the big parenthesis which is the brackets, and 30-25=5. now it's 5 +5=10<- that is the answer for 9. Do I need to explain more/ if not i hope this helps you better understand this.
