The base of a cylinder has a radius of 5cm. what is it’s area ?

78.5 cm²

Step-by-step explanation:

The area of a circle of radius r is πr².

Since the base of this cylinder is a circle, the area of the base is therefore:

π(5 cm)² = 25π cm², or approximately 78.5 cm²

the one below it is a function

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
