Answer:
Given:
- Diameter of a circle is 7 yards.
- Pi (π) = 3.14
To Find:
- The area and the Circumference of the circle.
Solution:
We know,
<u>Circumference of circle = 2πr² / πd </u>
where,
- π = 3.14
- Diameter (d) = 7 yd
➮ 3.14 × 7
➮ 21.98
Therefore, Circumference of the circle is <u>2</u><u>1</u><u>.</u><u>9</u><u>8</u><u>y</u><u>d</u><u>.</u><u> </u>
<u>Area of Circle = πr² </u>
where,
- π = 3.14
- Radius (r) = d/2 = 7/2 = 3.5 yd
➮ 3.14 × (3.5)²
➮ 3.14 × 12.25
➮ 38.48
Therefore, Area of the circle is <u>3</u><u>8</u><u>.</u><u>4</u><u>8</u><u>y</u><u>d</u><u>.</u>

CSA = Curved Surface Area
TSA = Total Surface Area
★ CSA of Cylinder = 2πrh
★ TSA of Cylinder = 2πr(r+h)
★ Volume of Cylinder = πr²h
★ CSA of Cone = πrl
★ TSA of Cone = πr(l+r)
★ Volume of Cube = (side)³
★ CSA of Cube = 4(side)²
★ TSA of Cube = 6(side)²
★ Volume of Cuboid = lbh
★ CSA of Cuboid = 2(l+b)h
★ TSA of Cuboid =2(lb+bh+hl)
★ TSA & CSA of Sphere = 4πr²
