How to find radius of hemisphere with surface area

- the
**surface area of a hemisphere**is 1062 cm^2. What is the**radius**? Hi Nicholas, The**surface area**of a sphere of**radius**r is 4 π r 2. Half of this is 2 π r 2. If this is what is meant by the**surface area of a hemisphere**then 2 π r 2 = 1062. Solve for r. If you have a hemispherical object then it has a base which is a circle of**radius**r. - The
**surface area**of a frustum is given by, A= 2πrl A = 2 π r l. where, r = 1 2 (r1 +r2) r1 =**radius**of right end r2 =**radius**of left end r = 1 2 ( r 1 + r 2) r 1 =**radius**of right end r 2 =**radius**of left end. and l l is the length of the slant of - Solution: Since it isn't mentioned whether we have to
**find**the total**surface area**of curved**surface area**, let us compute both. As we know, curved**surface area**of**hemisphere**=2πr2.**Hemisphere** **Surface Area**of a Sphere Practice Questions - Corbettmaths.
