Answer:
(x + 3)² + (y - 7)² = 81
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r the radius
here (h, k ) = (- 3, 7 ) and r = 9 , then
(x - (- 3) )² + (y - 7)² = 9² , that is
(x + 3)² + (y - 7)² = 81
Answer:
16
Step-by-step explanation:
Apply PEMDAS:
Solve the exponent, multiply from left to right, and then subtract and add from left to right.
The answer is 988 square inches. L=23 W=10 H=8
The equation for surface area is 2(L x W) + 2(L x H) + 2(W x H)
Next, you need to substitute the values into the equation to get:
Surface area= 2(23 x 10) + 2(23 x 8) + 2(10 x 8)
Now finish solving the equation to get an answer of 988 square inches!
