Answer:
531 cm^2 approx
Step-by-step explanation:
Given data
Diameter= 26 cm
radius= d/2= 26/2= 13 cm
Area= πr^2
substitute
A= 3.142*13^2
A= 3.142*169
A= 530.998
A= 531 cm^2 approx
(34 - R) will be the <span>expression of the other number</span>.
Volumes scale as the cube of a corresponding dimension. Therefore, if the radius of a sphere is doubled (r becomes 2r), the surface area becomes 2 squared, or 4 times the original surface area. The volume would become 2 cubed, or 8 times the original volume.
