What is sela's speed in yards per minute if her speed is 24 miles per hour

Circumference of the lily pad is about 28.3 ft

Area of the lily pad is about 63.6 ft²

Step-by-step explanation:

Formula for circumference of circle is,

Circumference = 2 π r

Given that diameter is 9 ft. Therefore radius is half of diameter.

Substituting the values,

Also value of π = 3.14

Substituting the value,

C = 2 × 3.14 × 4.5

Simplifying,

C = 28.26 ft

Rounding to nearest tenth value of circumference is C = 28.3 ft.

Formula for area of circle is,

A = π r²

Substituting the values,

A = 3.14 × 4.5²

Simplifying,

A = 63.585 ft².

Rounding to nearest tenth value of area is A = 63.6 ft².
