PLZ help me im fairly confused with all of these please dont answer if your just going for the points and not really helping me i really need help find the radius of a circle with a circumference of 25x yards

find the radius of a circle with an area of 280.13 square inches

find the diameter of a circle with an area of 615.75 cm squared

find the diameter of a circle with an area of 90.25x m squared

find the area of a circle with a circumference of 26x feet

find the circumference of a circle with an area of 289x mm squared

there r 2 formulas for circumference:  C= 2xpixr and c=pixd so use the one you need, plug in the values and solve

step-by-step explanation:

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
