Hey there,

Your question states: <span>What is the definition of circumference of a circle?

</span><span>Circumference is the circle it self so it would mean like 3.14 × diameter = 2 × 3.14 × radius. That is the way to define the circumference of a circle

I’m pretty sure the first one is 4 & the second one is 6; if that’s what you’re asking.

A solid metallic sphere of radius 7 cm is cut into two halves. Find the total surface area of the two hemisphere

svetoff [14.1K]

Here,
A sphere has 7cm radius
And it’s cut into tow half (2 hemispheres)
So, the radius of a hemisphere is also 7cm
Now,
TSA of hemisphere = 3 pie r^2
=3*22/7*7^2
=3*22/7*49
=3234/7
=462cm^2
Lastly,
The TSA of 2 hemispheres = 2* 462
=924cm^2

Hence,
The total surface area of the 2 hemisphere is 924cm^2
