## Is it possible to have the same numerical values for the volume and surface area of a sphere?

Area=4 x p x r2 square units. Similarly, its volume is 4 x p/3 cubic feet=2304 p cubic inches. Your question is meaningless. Every sphere will have the exact same numerical value for its volume, surface area, and length.

**What is the radius of a cone made from a quadrant of a circle of radius 28 cm? **

Curved area of the cone=prl. Where ‘r’ denotes the radius and the ‘l’ the slant height. The radius of the cone is therefore 7 cm. Answer.

### What is the radius and curved surface area?

Therefore the curved surface area (CSA) of the cone=616cm2. We now know that pr’l square units is the formula for the cone’s curved surface area (CSA)=616cm2. The radius of the circle is equal to the cone’s slant height. Therefore, l=r=28 cm.

**What is Cone CSA? **

The cone’s surface area is equal to its curved surface plus the area at the base. p r 2+ p Lr, pi R2 +pi Lr, pr2+pLr. r denotes radius of base and L denotes slant height. The lateral area is also known as the curved surface area.

#### What is curved surface area of a hemisphere?

The curved surface area for a hemisphere is 2pr2 units. The total surface area is the curved surface area plus the base area. The base of the hemisphere has a circular shape. Use the area of this circle to determine the area.

**What is the formula of CSA of sphere? **

The area of a disc enclosed by a circle with radius R is Pi*R2. Pi*R2 is the area of a disk enclosed by a circle with radius R.

## What is TSA and CSA of sphere?

Surface Area (TSA=CSA=4pr 2) Hemisphere: Curved surface area (CSA)=2pr 2. TSA=Total surface area=3 p.r. 2.
