http://prntscr.com/aozilv can someone just give me the steps i dont need an explaintion plz help

Answer 1

hello

Answer 2

did u read the question

Answer 3

?

Answer 4

whats the formula for area of a circle

Answer 5

A≈2463.01

Answer 6

?

Answer 7

A = pi * r^2
A = 22/7 * 14^2
A = 22/7 * 196
A = 615.9999

Answer 8

ok

Answer 9

so whats the first step i do to solve the question

Answer 10

radius is half the diameter

Answer 11

ok

Answer 12

start by writing formula

Answer 13

A≈2463.01?

Answer 14

no...area of circle
A = pi * r^2

Answer 15

ok the formula is A = pi * r^2?

Answer 16

?

Answer 17

then write
pi = 22/7

r = d/2....r = 28/2 = 14

now sub into the formula
A = 22/7 * 14^2
A = 22/7 * 196
A = 615.9999

Answer 18

ok so step 1 is A = pi * r^2 and second is pi = 22/7

r = d/2....r = 28/2 = 14?

Answer 19

ur listing what u know...pi = 22/7
and the other...d stands for diameter and r stands for radius

Answer 20

ok so what do i do for the first step im so confuised

Answer 21

write formula.....A = pi * r^2
write what u are subbing in....pi = 22/7
r (radius)....r = d/2...ur circle shows d = 28....so 28/2 = r...14 = r.
then just sub into the formula and do the math

Answer 22

pls help

Answer 23

Steps:
1. Write the formula for the area of a circle of radius r: A=pi*r^2
2. Determine the radius of this circle, given the diameter
3. Write out the formula for the area of the circle, subst. the given info:
A = pi ( r )^2

Answer 24

ok i got the formula

Answer 25

is ithe raiduis in the middle like the number in the middle?

Answer 26

Yes (although you need to spell it "radius").
