sunspots
The answer will depend on what the surface area is of. The surface areas of regular shapes are can be calculated from formulae but these will depend on the shapes. For non-regular areas there may or may not be simple formulae.
To calculate the surface area of a shape find the area of each side, and then, add all of the areas together. The sum of the areas is the surface area.
The surface area is the sum of all the areas of all the shapes that cover the surface of the object.
It would be the sum of the areas of each surface separately.
The ratio of their surface areas is 42 to 52 or 16 to 25
They are called sun spots, dark areas that are cooler than the rest of the surface.
Sunspots are cooler regions on the surface of the sun. Visually, they look like dark circles sporadically dotting the sun, and their numbers change from day to day.
It is called a sunspot.
Sunspots are the coolest areas on the surface of the sun
Sunspots are dark areas on the sun's surface that are cooler than the surrounding area.
What are the dark patches on the sun's surface called
A sunspot is a dark spot on the sun's surface. It is darker because it is cooler than most parts on the sun.
Photosphere- outer (gaseous) layer or surface of sun that we see Faculae- bright areas Sunspots- dark areas
Yes because there is a storm going on that causes it to cool.
Sunspots are dark areas on the sun's surface that are cooler than the surrounding area.
