4. “Find the area of this circle. Use 3.14 for x.(round to the nearest hundredth as well)” I WILL GIVE!

A = 153.86 ft²

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

   = 3.14 × 7² = 3.14 × 49 = 153.86 ft²

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
