1 2/6 as an improper fraction
gladu [14]

Answer:

=4/3

Step-by-step explanation:

Step 1

Multiply the denominator by the whole number

6 × 1 = 6

Step 2

Add the answer from Step 1 to the numerator

6 + 2 = 8

Step 3

Write answer from Step 2 over the denominator

8/6

=86

You can also reduce this fraction.

Find the Greatest Common Factor (GCF) of 8 and 6, if it exists, and reduce our fraction by dividing both numerator and denominator by it,

GCF = 2

=8÷2=4

6/2=3

Simplified Solution

=6×1+2/6 =8/6=4/3

hope this helps

you welcome and thanks

A dome-shaped structure is in the shape of a half-sphere. The diameter of the dome is 30 yards long, as shown below. What is the
Akimi4 [234]

Answer:

7068.58 yd³

Step-by-step explanation:

A half sphere would use the normal equation for the volume of a sphere and then divide it by two. The first step would be to find the radius of the sphere, which is half the diameter.

d=30 yd

r=d÷2

r = 30 yd÷2

r = 15 yd

Next, we need to use the volume of a sphere equation to find the volume of the full sphere.

V = 4×π×r³÷3

V = 4×π×15 yd³÷3

V = 4×π×3375 yd³÷ 3

V = 13500π yd³ ÷ 3

V = 4500π yd³

Next, we need to find the volume of the dome by dividing by 2.

V = 4500π yd³ ÷ 2

V = 2250π yd³

V = 7068.58 yd³

The total volume of the dome is 7068.58 yd³
