Find the volume of a sphere with a radius of 7 cm.

Find the volume of a sphere with a radius of 7 cm.

Step 1: Identify the formula for the volume of a sphere, which is Volume = (4/3)πr³.
Step 2: Substitute the radius (r) into the formula. Here, the radius is 7 cm.
Step 3: Calculate 7³ (7 cubed). This means 7 × 7 × 7, which equals 343.
Step 4: Multiply 343 by (4/3). First, calculate 4 × 343 = 1372.
Step 5: Now divide 1372 by 3. This gives you approximately 457.33.
Step 6: Finally, multiply 457.33 by π (approximately 3.14) to get the volume. This results in about 1436.76 cm³.

Volume of a Sphere – The formula for the volume of a sphere is V = (4/3)πr³, where r is the radius.
